Hi all,
I want to use an ODrive as a load controller for a dyno for testing other controllers and motors. This means I would be running it entirely within the regen braking regime. I have a few questions about this:
- Is there a way I can use the ODrive with only the logic power supply, instead only using braking resistors on the DC bus supply? How would I go about sizing those resistors?
- How accurately/precisely can I control very low torque loads if I’m using a low KV brake motor (such as the M8325s 100KV)? Ideally, I’d like one system to be able to work for testing both other low and high KV motors; it would need to have a range of something like 0.05Nm ~ 5Nm
- Are there any safety considerations I need to be concerned about when doing this (braking resistors coming disconnected and DC voltage spiking?)
Thanks for any advice you can offer me!
