Hardware limits

Can’t seem to find any hardware limits for current or rpm. Can someone point me in the right direction.

Take a look at this for current limits.

Odrive MOSFET temperature rise measurements using the onboard thermistor

Hey everyone I have been doing some testing on the thermal performance of an odrive V3.5 48V board. I expect results will be similar for all versions with the black heatsinks. The versions with the gold heatsinks may be slightly worse due to their lower quality thermal pads. tldr: Tests of the onboard thermistors show that they underestimate the MOSFETs temperature by 15C when operating at high currents and temperatures and so a safety margin of 25C is suggested. The measurements shown below…

Not sure about max RPM, usually the motor-bearings are the limiting factor for max rpm.
