Using ODrive + brushless as high speed electormagnetic brake system

Hi everyone ,

A project has come to my hands and i need a way to maintain the tension on a spool of paper that is being rewinded, the idea that i had is to connect a BLDC to the shaft where the spool is found and then program the ODrive to maintain a constant torque, if the tension on the paper spool is higher than the rated torque the motor should “slip” and let the spool rotate.

My question is, is there any risk of burning the controller if the spool is rotating at 2500 rpm (the brushless too)


No, not really. As long as you can dissipate that energy in your brake resistor (or you’re dumping it back to the DC bus)
