Electric Motor Torque Formula
The following formula is used to calculate an electric motor torque.
t = (I*V*E/100*60)/(rpm*2*pi)
- Where I is the current (amps)
- V is the voltage (volts)
- E is the efficiency of the motor (%)
- RPM is the rotations per minute
Electric Motor Torque Definition
Electric motor torque is the total torque generated by an electric motor given a current, voltage, efficiency, and RPM.
