ami 2013 uk franchised dealer report - Single-phase induction motors have a copper or aluminum squirrel cage embedded in a cylinder of steel laminations, typical of polyphase induction motors. Permanent-Split Capacitor Motor One way to solve the single phase problem is to build a 2-phase motor, deriving 2-phase power from single phase. • The three-phase induction motor is the extensively used for various kinds of industrial drives. • AC induction motors are also the most common motors used in main powered home appliances. Advantages of 3 phase induction motor • Generally easy to build and cheaper than corresponding dc or synchronous motors • Induction motor is robust. Because of this the motor sees a two-phase (unbalanced) current that results in a rotating magnetic field, as in a 3-phase machines. Once the motor has started, a centrifugal switch is used to disconnect the auxiliary winding, since a single winding is sufficient to sustain the motion of the rotor. assignments discovery education k 5 year plan
