Explain the working of motor in mixer.
Answers
he motor used in mixer grinder is generally a universal motor. The motor has stator and rotor. The stator is made of laminated steel. There are poles on the stator. Usually two poles are there. Field coils are wound on each pole. The rotor, also called armature is also made of laminated steel, has slots and is tightly fitted with the shaft. Rotor windings are placed on rotor slots. Ends of rotor windings are permanently connected to commutator segments. Commutator segments are around the shaft on one side. There are two brushes that make contact with two commutator segments at a particular instant. As shaft rotates, the commutator segments that come in contact with the brushes also change. Field windings in the stator and rotor windings are connected in series through the rotor commutator. Universal motor can run on both AC and DC. They have high starting torque and speed.
