can i use a switched-mode power supply instead of a battery for testing?
Power supply: 2kW Output 52V 40A BLCD Motor: 5KW 14S 220KV 100A
i use the controller to regulate a belt drive with a 35Kg Flywheel.
I change the some parameters for Battery management:
Motor Current Max: 100A
Motor Current Max Brake: -30A
Current Max Regen: = 0A
Battery cutoff start: 40V
Battery cutoff end: 35V
Battery Current Max: 40A
when the engine is running, i have peaks of over 60V at the input of the Vesc. the power supply supplies a constant voltage of 52V and have an adjustable overcurrent limitation. This peaks are not really nice. i think they damage my vesc msk controller board... what can i do? i will not use a battery for this application
I'm also using the vesc for a belt drive of a turntable and am wondering about using the switching power supply. Has this been working for you?
Yes you can. As long as you don't pull more current than the supply can provide and as long as you don't feed current back into the supply (regen). Most well designed switched supplies will have protections built in but you of course don't want them to happen in the first place. You have to watch out also for ground differentials on anything else you connect to the controller that uses power. Most commonly USB plugged into a laptop. Don't connect the 5v wire between the laptop and the controller. I use a 53v 15A supply mostly for initial testing. It has safety features to shut off if something goes wrong. There shouldn't be a problem running loads, but voltage spikes should be absorbed by the DC link capacitors. It's not clear what specific controller we are talking about, so can be the controller design issues. Definitely disable regen (that -30A setting).
