The rotor in a certain electric motor is a flat, rectangular coil with 88 turns of wire and dimensions 2.50 cm by 4.00 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, it carries a current of 9.9 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 3600 rev/min. (a) Find the maximum torque acting on the rotor. Tmax= N-m (b) Find the peak power output of the motor. Pmax = W (c) Determine the amount of work performed by the magnetic field on the rotor in every full revolution. W = (d) What is the average power of the motor? Pavg = W
Why do motors have gaps or breaks throughout the rotor and commutator? It makes the motor cheaper since not as much material is needed. Only some sections of the rotor will act as electromagnets, causing the rotor to always be pushed in the same direction. It allows some of the magnetic field to escape so that rotor doesn't get too stressed. It lets air into the motor to keep it cool since the electricity can make it hot. It happens when rotors don't use enough oil, so they crack.
