Hello,
I have to choose a contactor and a circuit breaker for a brushless drive BRU-200 but I don't know what I have to look up. The output of the drive is a sinusoidal output. I know :
motor : sine wave torque constant 0.74Nm/A
peak torque 19.7 Nm
drive : peak current per phase : 30A
nominal current per phase : 15A
output power : 3kW
DC bus voltage : 325V
input voltage AC 1-phase : 230V
How can I find the input current and the input power?
Thanks a lot.
