Frequently Asked Questions
Do BYD electric vehicles have a traditional engine?
No. BYD EVs use an electric drive motor (sometimes called an e-motor or traction motor) instead of a combustion engine. They also have a reducer gearbox (similar to a single-speed transmission) to transfer power to the wheels.
This page covers both components – as well as complete e-axle assemblies (drive motor + reducer + inverter combined).
How do I know which drive motor fits my specific BYD?
Use our VIN lookup tool. BYD uses different drive motors and gearbox ratios depending on:
Model (Atto 3, Dolphin, Seal, e6)
Year (pre-facelift vs. post-facelift)
Drivetrain (front-wheel drive vs. all-wheel drive – Seal Performance)
Provide your VIN, and we verify exact compatibility.
What are common signs of a failing BYD drive motor?
Common symptoms include:
Unusual whining or grinding noises from the motor
Loss of power or reduced acceleration
Vibration during driving
Error messages on the dashboard
Reduced regenerative braking efficiency
If you experience any of these, contact our EV specialists for diagnosis assistance.
Do you offer warranty on used drive motors and reducer gearboxes?
Used drive units typically include a 30-day warranty for fitment and defects. Genuine new BYD parts carry the full manufacturer warranty. Certified recycled components include a basic warranty (terms vary – ask our team).
Damage during transit is covered – inspect your part upon delivery and contact us immediately if any issues arise.
Can I return a drive unit if it doesn't fit my BYD?
Contact us within 30 days of delivery.
If the part doesn’t fit due to our error (wrong model, year, or side), we’ll arrange return and replacement at no cost to you.
If you ordered the wrong part, returns are accepted on unused items, but return shipping costs are your responsibility.
Do you ship large items like complete e-axle assemblies?
We carefully package large powertrain components using custom cartons, foam padding, or pallets depending on size and weight.
Shipping costs are calculated based on size, weight, and your location. We provide a quote before you commit. International shipping to NZ and Fiji is also available.
Do you sell drive motor controllers or inverters separately?
We supply motor controllers (inverters) and DC-DC converters as separate components. These are critical electronic parts that convert battery DC power to AC for the drive motor.
Note: Inverters and controllers are generally non-returnable once installed (unless defective upon receipt) – see our Return Policy for details.
