Description
About the Nissan Leaf Engine
This is the EM57, the electric drive motor used in the second-generation Nissan Leaf, a permanent-magnet AC synchronous motor with neodymium magnets and the inverter integrated into the motor assembly, as the live page describes. Mounted transversely for front-wheel drive, it delivers the immediate, smooth torque that defines EV driving, with whisper-quiet operation and full support for regenerative braking. The integrated motor-and-inverter design saves space, reduces wiring, and improves cooling compared with the earlier-generation unit, and it pairs with the Leaf’s high-voltage battery and onboard charging hardware.
Why Leaf Owners and EV Builders Choose This Motor
Owners replace the drive motor after a fault or high mileage, and EV builders choose the EM57 for its compact, integrated design and proven torque. A sound unit restores the Leaf’s quick, quiet acceleration and one-pedal regenerative feel, and for a conversion it provides a well-documented, widely supported motor to build around, after you review power requirements and mounting.
Things to Confirm Before Ordering
- Your year and variant, confirmed by VIN; the donor is tagged 2018 while the description mentions 2019, and power differs between the 40 kWh Leaf and e+ models
- Your high-voltage compatibility: per the live FAQ, pair it with the standard Leaf onboard charging hardware and a compatible battery pack, and for a swap review power requirements and mounting first
- Your care plan: per the live FAQ, this is an electric motor, so it needs periodic coolant checks, connector cleaning, and controller firmware updates, not engine oil or spark plugs
