GS450H gearbox with Camry inverter G9200-33171 [SOLVED]

I wasn't aware of your local fabrication limitations. Do you order from JLCPCB? They do CNC machining pretty affordably. If you get both sides correct, pump and transmission i could use those and make you a step file or 2.

An esc is about speed. A vesc can be programmed for torque, speed, or have a script run it.
I think the official 4.x VESC hardware can run down to 8 volts. The Toyota pump should run fast enough on 12v to make all the pressure you need. You should not have to use field weakening. Basically I think it will be much more controllable with a VESC. The need for a position sensor in an oil pump is silly.

have you used VESC?
i wasnt able to find a seller of those so i could try it out.

VESC is similar to open inverter but for small motors. People use them on skateboards, scooters, and some have been converted to run cars. It's open source and requires anyone selling one to not use the vesc name which makes them challenging to find.

I've used 2x "FLIPSKY 75100 Pro V2.0 75V 100A with Aluminum PCB" so far on projects. USB has worked well, Bluetooth has been challenging but I'm also using scripts. These drop out around 12v I think so probably not ideal. They claim 4s at the low end. I can test mine to check the min voltage if you want. But a low battery will also mean no drive if you use one of these.
