EM61
editThe EM61 made its debut in 2010. It was used only in the first generation Nissan Leaf (ZE0 2010-2012). The EM61 generates 280Nm of peak torque.
EM57
editThe EM57 is an improvement over the first generation. It was first released with the AZE0 Nissan Leaf refresh in 2013. This motor features a smaller footprint, allowing for 11.7 kg of weight savings in the inverter/motor package[1]. The motor also trades some peak torque for a more efficient power range[2]. It peaks at 250Nm of torque.
It is used in the following vehicles:
- Nissan Leaf (AZE0 2013-2017)
- Nissan e-NV200 (2014-Present)
- Nissan Leaf (ZE1 40kWh, 2018-Present)
The EM57 motor can be run at different power levels. For instance in the AZE0 Nissan Leaf it runs at 80kW max power, but when fitted into the ZE1 Nissan Leaf it runs at 110kW max power.
