What is the power output in horse power of an electric motor turning at 4800 rev/min and developing a torque of 4.30 Nm ?

What is the power output in horse power of an electric motor turning at 4800 rev/min and developing a torque of 4.30 Nm ?

Answer:=>

Frequency =4800Rev/min=80rev/sec

Angular velocity=w=2πf=160π rad/s

Power developed =torque×angular velocity

=4.3×160π

=2161.41 watt

Now

746 watt=1 horse power(hp)

2161.41 watt=2.89 hp
