Hey,
I am using Odrivr 3.6 to control a scooter motor (Xiaomi M365). I have a 2 ohm braking resistor and a 24V power supply. When I turn the motor manually too fast, the DC bus reaches 25V, while the resistor only burns 1 A. Shouldn’t Odrive be able to burn 24 V / 2 Ohm before the bus voltage increases?
How are you measuring the 1A across the resistor? I’d double check the connections, and make sure there isn’t a high resistance connection in there accidentally (e.g. an alligator clip). It could also be the case that you’re just overspeeding the motor (making the back-emf voltage higher than the bus voltage), which the ODrive is unable to deal with.
