A motor generates an output power of 220 W at an angular velocity of 2100 rpm. Calculate the torque ( in Nm ) produced by the motor ? [ Take `pi= ( 22)/( 7) `]

Text Solution

Verified by Experts

The correct Answer is:

746

`omega=2100 xx(2pi)/60 = 70 pi ` rad/s
Power `= tau omega`
`:. tau = P/omega= (220xx746 xx7)/(70 xx22) = 746` Nm
