explain electric motor 10th class
Answers
Explanation:
Electric motor is a device that converts electrical energy to mechanical energy. Magnet Poles: A magnet as placed above ie North Pole and South Pole. This creates a magnetic field as shown above. Axle: The split rings are placed on the axle which can rotate freely.
=> An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.
=> The field winding generates a constant dc flux. The armature conductor which carries current experiences force and the direction of this force is given by Fleming's left hand rule. Thus the motor starts rotating. The 3 phase induction motor works on the principle of induction.
=> The main parts of an electric motor include the stator and rotor, a series of gears or belts, and bearings to reduce friction. DC motors also need a commutator to reverse current direction and keep the motor spinning.
