Break-down torque ratio
WebYou are correct that F*r = torque, and that angular velocity is rad/sec. To see why P = 2pi(torque)*(angular velocity) plug in the units rad/revolution next to 2pi, and like the article says plug in rev/sec next to angular … Webgle to each other. Net torque from current in phase with the induced voltage and torque component with no net torque, just vibration, from current at 90 deg. phase angle. Notice that the torque equation implies a relationship between the size of the rotor and the mechanical power that can possibly be delivered to the load. The mechanical power is 0
