Toyota/Lexus MGR Rear Transaxle Motor

2022-12-14T22:30:40Z

Cajunfj40: Reformatted first part of list, added gear ratios, layout, capacity as found on a new source, with cites.

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, potential need for additional cooling dependent on the application

Toyota P510 CVT

2022-12-14T22:08:04Z

Cajunfj40: Added a bunch of gear ratio specifics from a few references. Per the Weber Auto videos, the PSD has the same gearing as the P310 and P410. Couldn't find info on the final drive tooth count.

== Description ==
The P510 is considered a third generation e-CVT and very similar to the P410 transaxle. The transmission is passively air cooled and thus has no antifreeze circulating through it.

=== Model Code ===
1LM

== Applications ==

* Toyota Prius C (2012-2021)
* Toyota Yaris Hybrid
* Toyota Corolla Hybrid

== Specifications ==

=== MG1 ===
Rated Voltage: 520V

Max Output: 42.4kW (56hp)<ref>https://www.greencarcongress.com/2012/02/priusc-20120208.html</ref>

MAX RPM: ?

=== Power Split Device (PSD)<ref name=":0">https://www.youtube.com/watch?v=pFug8jwbbTE</ref> ===
Planetary gears (4x) 23 teeth - carrier connected to transaxle input shaft and oil pump

Sun gear 30 teeth - connected to MG1

Ring gear 78 teeth - inside Drive Gear

Locked input shaft (stationary carrier) gives -2.6:1 ratio from MG1 to Drive Gear

=== MG2 ===
Rated Voltage: 520V

Max Output Power: 45 kW (60.3 HP)

Max Output Torque: 169 Nm (124 lb-ft)

Max RPM: ?

=== Motor Speed Reduction Gearset (MSR)<ref name=":0" /> ===
Planetary gears (5x) 18 teeth - carrier connected to case/fixed.

Sun gear 22 teeth - connected to MG2

Ring gear 58 teeth - inside Drive Gear

MG2 to Drive Gear ratio 2.636:1

=== Final Drive Ratio<ref name=":0" /> ===
Drive Gear 55 teeth - contains PSD and MSR ring gears

Counter Driven Gear 54 teeth - on same shaft as Final Drive gear

Drive Gear to Counter Driven Gear ratio 1.0815:1

Final Drive Ratio 3.132:1

MG2 to axle output total gear ratio 8.410:1

MG1 to axle output total gear ratio with locked input shaft 8.807:1

=== Oil Pump ===
Trochoid pump driven by engine shaft. The pump is mounted externally on the case and is considerably larger than the P410 pump since the transaxle relies primarily on oil cooling. There are two oil distribution tubes within the transaxle that distribute oil from the oil pump to oil directors mounted on the end windings of both MG1 and MG2.<ref name=":0" />

=== Fluid Capacity ===
??L of Toyota WS fluid.

=== Dimensions ===

=== Weight ===
176 lbs<ref name=":0" />

== Connections ==

=== MG1 Stator ===

=== MG2 Stator ===

=== MG1 Resolver ===

=== MG2 Resolver ===

=== Park Shift Cable Linkage ===
