What does anyone think about this motor.

The VIN on the transaxle tells me it is from a 2001 prius hybrid. I got the motors spinning last week using a couple of motor control boards and a small inverter. The transaxle has two large brushless DC motors inside. The whole unit has transmission fluid inside dripping through the stator and rotors of each motor and the housing has water cooling jackets for each electric motor. MG1 and MG2 are connected by a planetary gear with the planet carrier shaft protuding where the hybrid ICE would connect. MG2 connects to a differential with a 4.11 to 1 gear ratio.
In the video I am driving MG2 which is the larger of the two motors and MG1 is held stationary. My test setup in the video is only using 24 VDC limited at 3Amps. The output of the differential spins at 1.6 rev/sec with my 24V supply. I calculate this would equal 6.8 mph with a 24inch tall tire. So I would expect to be able to go 68 mph top speed if I had a 240 volt battery pack since my understanding of brushless dc motor speed to voltage relationship is linear.
In the video you can hear some grumbling of the gears. I'm not 100% sure I put it back together perfectly and there isn't any fluid in it right now. Or maybe that is why it was scrapped in the first place.
My wife just texted me and said a large box just arrived at the house. I would assume that this is the High Voltage prius inverter that I ordered from a wrecked 2002 prius. My goal is to use this transaxle and the prius HV inverter with my own control unit design for my electric volkswagen project.
I assume that if this motor worked for a prius then it would work well for my ev. Not sure.
Has anyone used this motor before or have they built their own controller for the prius inverter?
Thanks
Jeff
