Find the maximum torque acting on the rotor

Reference no: EM13493576

The rotor in a certain electric motor is a flat, rectangular coil with 81 turns of wire and dimensions 2.57 cm by 4.32 cm. The rotor rotates in a uniform magnetic field of 0.800 T. When the plane of the rotor is perpendicular to the direction of the magnetic field, the rotor carries a current of 11.1 mA. In this orientation, the magnetic moment of the rotor is directed opposite the magnetic field. The rotor then turns through one-half revolution. This process is repeated to cause the rotor to turn steadily at an angular speed of 3.45 103 rev/min.

(a) Find the maximum torque acting on the rotor.

(b) Find the peak power output of the motor.

=0.288 W

(d) What is the average power of the motor?
