Hi,

We’re to use these sort of braking resistors:

Arcol 2Ω Non-Inductive Resistor 50W ±1% AP851 2R F 300PPM | RS Components (rs-online.com)

I was wondering since the odrive itself came with a 50W resistor and i have not found any values much higher, maybe a 100W, on this forum… is 50/100W a safe option for our motor?

We run the motor at 48V and take for the max current about 20 Amps, but it is rated for a max of 1750W. How does this 1750W relate to the braking resistor. Especially in the case that this resistor is only rated for 50 or 100W depending on the one we choose. I’ve found that this can be (a lot) higher for just peak moments but still.

Can one explain the theory behind this a bit and maybe a little bit of advise / tips too look into the correct value for a braking resistor.

And, does an ‘overpowered’ braking resistor also exists? I mean, I’m not too afraid to just implement enough margin in terms of power rating and resistance if that’s what it takes.
