Hello all, I have a few questions about calculating efficiency, torque and horsepower for a small pulse dc motor. The only parameters that I have are input voltage = 39Vdc, input current = 2A and rpm = 90,000 rpm. Are the above values obtainable with the given information? This is not a homework problem per se. It is homework in the sense that I am a hobbyist and I've built the motor with the values I've provided at home. Thank you in advance for any help provided.
