An EZGO electric motor is the drive unit that turns battery voltage into wheel torque on every electric TXT, RXV, Express, Liberty, and Terrain cart.
When the motor fails, the cart loses power on a driveway grade it climbed last month. A burning smell shows up after ten minutes. The controller throws a fault code, and the cart stops moving.
Few things frustrate an owner more than a cart that will not pull its own weight.
Motor selection is where replacement jobs go wrong. EZGO built 36V PDS, 48V DC, and 48V AC carts across two decades, and the motors do not interchange. Ordering by voltage alone is not enough.
Three problems show up again and again:
- An owner orders a 48V motor for a 36V TXT and the controller cannot support it.
- A standard Express S4 motor lands on a High Output cart and strains under passenger load.
- An older RXV owner buys a bare AC motor and learns the cart needs an adapter harness.
Carts & Parts stocks genuine OEM E-Z-GO motors for every platform and confirms fitment by serial number before shipping. The guide below covers how to identify your platform and which ezgo electric motor part number matches it.
Key Takeaways
What is an EZGO electric motor and which platforms use one?
An EZGO electric motor is the DC or AC drive unit bolted to the rear axle on every electric TXT, RXV, Express, Liberty, Terrain, and 2FIVE cart. TXT and Express carts use brushed DC motors on 36V or 48V systems, while RXV, Liberty, and ELiTE carts use brushless 48V AC motors matched to an AC controller.
Which OEM motor fits a 48V DC EZGO TXT or Express?
The OEM EZGO 48-Volt DC Motor, part number 624105, fits 2010 to 2022 TXT 48V, 2017 to 2022 TXT ELiTE, 2020 to 2023 Valor and Valor 4, 2012 to 2023 Express S4 and L4 48V, and 2012 to 2019 Terrain 250. The 624105 motor is built by Advanced Motors & Drives and replaces the older 612624 unit.
Which OEM motor fits a 36V PDS EZGO?
The OEM EZGO 36-Volt PDS Electric Motor, part number 624106, is the factory replacement for 36V TXT carts equipped with the Precision Drive System. The 624106 motor uses Advanced DC construction with regenerative braking designed for the PDS controller.
Which OEM motor fits an EZGO RXV or Liberty AC cart?
The OEM EZGO 48-Volt AC Electric Motor, part number 680638, is the Mahle AMT7132 three-phase motor rated at 3.3 kW for RXV, Liberty, Express ELiTE, and Cushman ELiTE carts. Owners replacing a legacy AC motor on 2008 to 2015 RXV and 2FIVE carts order the 671143 kit, which adds the conversion jumper harness.
How Do You Know Which EZGO Electric Motor Your Cart Needs?
EZGO electric carts fall into three motor families: 36V PDS DC motors on earlier TXT carts, 48V DC motors on later TXT, Express, and Terrain carts, and 48V AC induction motors on RXV, Liberty, and ELiTE carts. Each family uses a different controller and motor design. Two checks narrow five part numbers down to one.
What Do 36V and 48V Mean for Motor Selection?
Pack voltage tells you which motor windings your cart was built around. Six 6-volt batteries make a 36V system. Six 8-volt batteries make a 48V TXT system, and four 12-volt batteries make a 48V RXV system.
A motor wound for 48V runs weak on 36V, and a motor wound for 36V overheats on 48V. Count the batteries and read each label before you shop.
Battery layout, cable routing, and charger matching for each system are covered in the EZGO golf cart batteries and electrical parts guide.
How Do You Read Your Serial Number to Confirm the Platform?
The EZGO serial plate sits on the frame near the driver-side rear wheel on most TXT carts and inside the passenger-side glove box or under the seat on RXV carts. The model code and year on that plate settle the platform question.
A 2015 Express S4 and a 2015 Express S4 High Output share a body but not a motor. Decoding help by year and model is available in the EZGO serial number list.
What Does a Correct OEM Motor Replacement Look Like?
Genuine OEM E-Z-GO motors from Advanced Motors & Drives, NIDEC, and Mahle match the brush grade, shaft spline, mounting bolt pattern, and speed sensor interface of the motor that came off the cart. Carts & Parts has earned more than 1,550 online reviews with a near-perfect rating by matching the exact part to the exact serial number.
Ed Greenrod needed a part that would work the first time and found the process simple:
“Carts and Parts were a great help with getting my cart back up and going. The part fit perfect, worked perfect, the price point of my part was great and the process was easy. I recommend them for sure. The coozies were a nice add.”
Every OEM component category, including motors, controllers, and drivetrain parts, is covered in the EZGO golf cart parts guide.
What Is the Four-Step Plan Before Ordering an EZGO Motor?
Four steps prevent nearly every wrong-motor order:
- Confirm pack voltage by counting the batteries and reading the voltage stamped on each case.
- Photograph the serial plate and note the model code, year, and any High Output or ELiTE designation.
- Test the controller, solenoid, and battery cables before condemning the motor, since those parts fail more often.
- Call or text (937) 459-8891 with your model and serial number so our team confirms the part number before you pay.
Which EZGO Electric Motor Fits a 36V PDS TXT?
The OEM EZGO 36-Volt PDS Electric Motor, part number 624106, is the factory replacement for TXT carts running the Precision Drive System on a 36V pack. PDS carts use an Advanced DC motor with regenerative braking, so the motor and controller work as a matched pair.
Symptom: the cart slows on hills it used to climb and the motor housing gets hot enough to smell.
Cause: worn brushes or damaged windings reduce the motor’s ability to convert current into torque, so it draws more amperage and generates heat instead of motion.
What it means: the motor is near the end of its service life, and continuing to run it risks damaging the PDS controller.
💡 Tip: PDS controllers fail in ways that mimic motor failure, including sluggish takeoff and no reverse. Test the controller first. Owners often save the price of a motor by fixing the controller.
John Shekell ran into exactly that situation on his 36V cart and got a diagnosis instead of an upsell:
“Very helpful and interested in helping me solve my ez go 36 volt problem. The exchange program for a bad speed controller was a big dollar saver!! Shipped on time and worked as Cole said it would. Always good to work with a company that lives up!!”
The 624106 ships as a single motor assembly. Confirm your PDS model year with our team before ordering.
Which 48V Motor Fits TXT, Express, and Terrain Models?
The OEM EZGO 48-Volt DC Motor, part number 624105, is a brushed DC motor built by Advanced Motors & Drives (model DL9-4006) that replaces the older 612624 motor across the 48V DC lineup.
Coverage includes TXT 48V, TXT ELiTE, Valor, Express S4 and L4 48V, Terrain 250, and Cushman Shuttle 2+2 and Hauler 800X.
The same motor is also sold as the 750438PKG kit, which bundles the 624105 motor assembly with the 627215 O-ring plug kit. Order the kit if your old motor’s plug seals are worn, or the bare 624105 if you only need the motor.
| Platform | Model Years | System | OEM Motor |
|---|---|---|---|
| EZGO TXT 48V | 2010 to 2022 | 48V DC | 624105 (replaces 612624) |
| EZGO TXT ELiTE | 2017 to 2022 | 48V DC | 624105 |
| EZGO TXT Valor / Valor 4 | 2020 to 2023 | 48V DC | 624105 |
| EZGO Express S4 / L4 48V (standard) | 2012 to 2023 | 48V DC | 624105 |
| EZGO Express S4 High Output | 2014 to 2021 | 48V DC (High Output) | 628660 (not 624105) |
| EZGO Terrain 250 | 2012 to 2019 | 48V DC | 624105 |
| Cushman Shuttle 2+2 | 2015 to 2022 | 48V DC | 624105 |
| Cushman Hauler 800X | 2014 to 2018 | 48V DC | 624105 |
Symptom: acceleration hesitates from a stop, then surges once rolling.
Cause: brush wear or a scored commutator interrupts current flow at low RPM, where the motor draws the most amperage.
What it means: the motor still works but is failing under load, and the controller is absorbing electrical stress it was not designed for.
⚠️ Important: The 624105 includes the motor assembly only. Inspect your speed sensor, mounting hardware, and motor cables before installation day so the job does not stall waiting on a small part.
DC motors and AC motors follow different diagnostic paths and different replacement rules. Owners unsure which system they have can compare both in the AC vs DC golf cart motors guide before ordering.
When Does an Express S4 Need the High Output Motor?
The OEM EZGO 48-Volt Electric Motor for Express S4 High Output, part number 628660, is a NIDEC Drive Systems motor (ID DV1-4001) rated at 2.4 kW with an S2-60 minute duty rating for 2014 to 2021 Express S4 High Output carts. Fitment excludes ELiTE, lithium, and 72-volt models.
Situation: two Express S4 carts from the same year sit side by side, and only one carries the High Output designation.
Insight: EZGO gave the High Output configuration a heavier-duty motor for sustained passenger and cargo loads. Installing the standard 624105 on a High Output cart leaves the drivetrain underpowered.
Recommendation: read the model designation on the serial plate and match the motor to it. When the plate is worn, send us a photo of the existing motor label and we will identify it.
What Golf Cart Electric Motor Do RXV and Liberty Owners Need?
The OEM EZGO 48-Volt AC Electric Motor, part number 680638, is a Mahle AMT7132 three-phase AC motor rated at 3.3 kW with Class H insulation for RXV, RXV Valor, Express ELiTE, Liberty, and Cushman ELiTE carts. It replaces the earlier 666986 motor.
The 680638 ships with the OEM speed sensor (614252 / 687424) and three factory-length power cables. Installed with the OEM controller on a compatible cart, it requires no programming.
Component: a brushless AC motor with no commutator. Process: the AC controller converts 48V battery power into three-phase current while the speed sensor feeds rotor position back. Outcome: smooth acceleration, regenerative braking, and no brush service.
Three-phase induction motors are measured and rated for efficiency using methods described in the U.S. Department of Energy motor selection handbook, which explains why losses matter across a motor’s full service life.
How Does EZGO Motor Replacement Work on Older AC Carts?
The OEM EZGO 48-Volt AC Electric Motor Kit, part number 671143, bundles the 680638 Mahle motor with a 672067 conversion jumper harness, the OEM speed sensor, and three power cables so the current motor platform installs on carts built with discontinued AC motors. The kit replaces part numbers 601882, 611355, 614530, and 614530PKG.
Fitment covers 2008 to 2025 RXV, 2010 to 2015 2FIVE, 2016 to 2026 Liberty and Liberty LSV, 2016 to 2025 Express S2 and S4 AC models, and 2012 to 2015 Cushman LSV 800.
Installation follows a short sequence:
- Disconnect the battery pack and confirm zero voltage at the controller before touching motor cables.
- Label the three motor phase cables and the speed sensor connector before removal.
- Install the 671143 motor and route the 672067 jumper harness between the sensor and controller.
- Reconnect, power up, and confirm forward, reverse, and regenerative braking before road use.
🚨 Warning: 2008 and 2009 RXV carts and 2010 2FIVE carts also require the Speed Sensor to Encoder Adapter Harness, part number 612259, sold separately. Without it, the controller cannot read motor position and the cart will not move.
Owners considering higher-output motors for greater speed should know that the National Highway Traffic Safety Administration has addressed modified golf carts directly, explaining how a speed increase beyond 20 mph changes which federal safety standards apply on public roads.
What Happens If You Run the Wrong Motor?
A mismatched EZGO motor shortens the life of every part wired to it. Common outcomes include:
- Controller failure within days when an AC motor is paired with a DC controller or a 36V motor is run on 48V.
- Overheated cables and connectors as the motor draws amperage outside its design range.
- Repeat motor replacement when a standard motor is installed on a High Output cart and fails under load.
- Loss of torque on a grade, which creates a real safety problem with passengers aboard.
What Does the Right EZGO Motor Feel Like After Installation?
The correct OEM EZGO motor, matched to the platform and controller, restores factory behavior on the first drive:
- Acceleration is smooth from a standing start with no hesitation or surge.
- Speed holds steady on inclines with a full load of passengers.
- The motor runs quiet, with no buzzing, sparking, or burning smell.
- Regenerative braking on AC carts and PDS carts engages the way it did when the cart was new.
John Landen saw exactly that outcome on a cart most owners would have written off:
“Did a great job of bringing our old electric golf cart back to life.”

Frequently Asked Questions About EZGO Electric Motors
What voltage is my EZGO electric motor?
Your EZGO motor voltage matches your battery pack. Six 6-volt batteries equal 36V, six 8-volt batteries equal 48V on a TXT, and four 12-volt batteries equal 48V on an RXV. We can confirm from your serial number if you are unsure.
Can I put a 48V motor in a 36V EZGO?
Installing a 48V motor on a 36V pack produces weak performance because the windings were designed for higher voltage. A full 36V to 48V conversion requires new batteries, controller, solenoid, charger, and cables along with the motor. We recommend replacing a 36V motor with the OEM 36V unit.
What is a PDS motor on an EZGO TXT?
PDS stands for Precision Drive System, an EZGO 36V TXT drivetrain that pairs an Advanced DC motor with a controller providing regenerative braking and speed control. The OEM replacement is part number 624106. You need a PDS-specific motor because the controller depends on it.
How do I know if my EZGO has an AC or DC motor?
RXV carts built from 2008 onward, Liberty, and ELiTE carts use AC motors. TXT, Express, and Terrain carts use DC motors. DC motors have a removable brush end cap held by hex screws, while AC motors have a sealed housing. We can confirm from your serial number in seconds.
Does the OEM EZGO AC motor include the speed sensor?
Yes. The 680638 AC motor ships with the OEM speed sensor (part 614252 / 687424) and three factory-length power cables. The 671143 kit adds a 672067 conversion jumper harness for carts built with discontinued AC motors. You install both without controller programming on compatible carts.
What EZGO motor replaces part number 612624?
The OEM EZGO 48-Volt DC Motor, part number 624105, is the direct replacement for the discontinued 612624 motor. It fits 2010 to 2022 TXT 48V, TXT ELiTE, Valor, Express S4 and L4 48V, and Terrain 250. We stock it and ship it nationwide.
What is the difference between the Express S4 standard and High Output motor?
The Express S4 High Output configuration uses the NIDEC 628660 motor, rated at 2.4 kW with an S2-60 minute duty cycle for sustained loads. Standard 48V Express S4 carts use the 624105 motor. Your serial plate and model designation tell you which one your cart needs.
Do 2008 and 2009 RXV carts need an adapter for the new AC motor?
Yes. 2008 and 2009 RXV carts and 2010 2FIVE carts require the Speed Sensor to Encoder Adapter Harness, part number 612259, in addition to the 671143 kit. We will add it to your order when your serial number falls in that range.
How long does an EZGO electric motor last?
Brushless AC motors on RXV and Liberty carts commonly run ten years or more without motor-specific service. Brushed DC motors on TXT and Express carts depend on brush condition and load. Worn brushes announce themselves through power loss and heat, so testing before replacement saves you money.
Does Carts & Parts ship EZGO motors nationwide?
Yes. We ship genuine OEM E-Z-GO motors to every state, with free shipping on orders over $50. Call or text (937) 459-8891 with your model and serial number and we will confirm fitment before the motor leaves Union City, Indiana.
