So far I have not found any limits in both directions. So wil be have the same regardless.
Has anyone every asked for more then 200Nm over can to see what it would do?

Code: Select all
void canRX_289(const CAN_message_t &msg)
{
motorTorque = ((((msg.buf[0] * 256) + msg.buf[1]) - 10000) / 10); // Motor Torque -200 / + 200nm
motorRPM = (msg.buf[2] * 256 + msg.buf[3] - 20000); // Rear RPM -10000,10000,RPM negative is reverse
Was resolver polarity in the end! Spinning the correct way now.
Can you now also spin in reverse with a negative torque command?

I'm trying to find the maximum width of the rear motor package including gearbox and mounts, see red markings in picture. Please, is there anyone who can share this dimension?

Curiously no. Spins the same way regardless of positive or negative torque commands. I have the gearbox so doesn't affect me. But obviously still not ideal.
No problem, the motor is just sitting on the garage floor at the moment so its easy to take measurements if you need anything else.
Well the OC events leads me to believe one of the phases is shorting the motor casing probably. If one phase is shorting into the other you would get constant resistance to turning.bobby_come_lately wrote: ↑Fri Sep 16, 2022 8:58 pm Thought you might be interested to know in this thread that I seem to have destroyed an Outlander rear motor. Not sure of the cause yet, but as you can see in latest vid, it ain't spinning any more.
Current suggestions of cause (I have no idea yet):
- Bearing failure due to poor alignment
- Overheat/burnout due to failed cooling/too much current
I'm going to get the faceplate off and take a look when I can get back to the garage.
Well did you hear any bearing noises with motor accelerating or shifting?bobby_come_lately wrote: ↑Sat Sep 17, 2022 5:42 am
I hadn't considered longitudinal pressure on the shaft. That's a possibility if my measurements were out. I did screw that up first time around, making my coupler too long. I thought I fixed that but it is a definite possibility.
Yikes. Time to dig through skf and find replacements!bobby_come_lately wrote: ↑Sat Sep 17, 2022 12:10 pm Opened it up and it's pretty obvious - total bearing failure.

I am very interested in coming up with a drive shaft/flange solution as getting the shafts is getting difficult.
The company im working with whom are cold rolling the stubs i have designed for the leaf gearbox, do all the oem prototypes. theyll have no problem making a stub for these.
