My DC motor's nameplate says:
HP: 4 HP
RPM: 5000 RPM
I chose this IGBT IKW50N60DTP to drive the motor with a PWM frequency of 5 kHz using a single-quadrant chopper.
My question is: For the power calculations, do I need the max load current of 27A (average IGBT current value?), even if I don't plan to reach that value of current?
I'm following this app note to do my power calculations and it suggests I need the IGBT average and RMS current.
