there are a large variety of electric motors, the two main types are:

AC motors

AC motors take some form of alternating current and convert it into torque.

there are a large variety of ac motors available, and all modern evs and hybrids use some type of a AC motor.

3-phase AC motors require some form of inverter to drive and control them.

DC motors

DC motors are an old technology no longer used in ev's. they generally are not worth your time.

controlling them requires a very simple voltage regulator.

This page is intended as a listing page for available motors suitable for conversion projects. Each listing is planned to lead to a more detailed page regarding the motor.

Found on numerous Toyota and Lexus models (see list to the left), the MGR (or Motor Generator Rear) is an electric rear differential meant to provide occasional 4WD/AWD to the company's larger 4WD models.

For conversion/project purposes the MGR is suitable for lighter models given the torque available or could potentially be used front and/or rear, and/or with a secondary motor.

As the motor was designed to be used occasionally as a rear motor, there is a need or potential need for cooling dependent on the application.

GS450h L110 Transmission.jpg
Lexus GS450h Toyota/Lexus Lexus GS450h L110 RWD Popular conversion project motor, the GS450h has two motors as part of a gearbox mated to an ICE engine. MG1 and MG2, one of which is generally used to start the ICE, the second used to provide drive to the wheel in electric only mode.

The input shaft from the ICE can be secured and both motors can then be used to drive the output shaft.

The popularity and conversation around it comes from the fact it is likely to occupy the same space as a rear wheel drive gearbox leaving the majority of the engine bay free and obviously joining to the existing rear propshaft.

L110f AWD Functionally the same as the GS450h(?) but splits the output front and rear like a traditional 4WD gearbox.
Lexus GS300h Toyota/Lexus Lexus GS300h L210 RWD Very similar to the GS450h setup.
Prius Transaxle Toyota/Lexus Prius (1998-2003) P111 FWD Mated to a transversally mounted front wheel drive ICE, the Prius transaxle has two motors contained with it. MG1 and MG2. One of which is generally used to re/start the ICE motor and the second used to drive the car in electric only mode.

The two motors can be combined for greater power output.

The unit itself lends itself to replace the engine and gearbox from FWD front engined vehicles as it largely occupies a similar space as the existing gearbox and frees the space where the engine would sit.

Outlander Rear Motor.jpg
Mitsubishi Outlander Rear Drive Unit Mitsubishi Outlander PHEV Y61 RWD This motor is found on the Mitsubishi Outlander PHEV. It is the motor which drives the rear differential unit. There may be 3 different versions of this motor - 50kW, 60kW and 70kW (from PHEV 2018 on). The same motor may also be used in the i-MiEV.

The Openinverter Forum has a dedicated board here:

Hyundai/Kia HSG Hyundai/Kia Designed as a belt driven starter/generator for Kia/Hyundai's hybrid vehicles. Rated ~8kW, but capable of more. Water cooled, with 3 phase input and resolver and temp outputs.
Alternators Various Certainly low power, questionable efficiency, the main attraction with these is their robustness and low cost. The ability to drive the field coil directly opens interesting characteristics...
