Three-phase induction motor

Feb 21, The starting torque of an ordinary squirrel-cage motor (the other is double-caged) is limited to approximately twice the total load torque when total voltage is applied to the stator winding and under these conditions the starting current is five to eight times its full charge value Construction of 3 phase induction motor:Double-Cage Rotors: Double-Cage Rotors An induction motor with two rotor windings or cages is used for obtaining high starting torque at low current The stator of a double cage induction motor is similar to that of ordinary induction motor.

Double Cage Induction Motor: Construction, WorkingThree Phase Induction Motor

Double Cage Induction Motor One of the advantages of the slip-ring motor is that resistance may be inserted in the rotor circuit to obtain high starting torque (at low starting current) and then cut out to obtain optimum running conditionsJust like any other motor, a 3 phase induction motor also consists of a stator and a rotor Basically there are two types of 3 phase IM - 1 Squirrel cage induction motor and 2 Phase Wound induction motor (slip-ring induction motor) Both types have similar constructed rotor, but they differ in construction of rotor This is explained further.

Three Phase Induction Motors

Those induction motors which employ squirrel cage rotor are called squirrel cage induction motors Most of 3-phase induction motors use squirrel cage rotor as it has a remarkably simple and robust construction enabling it to operate in the most adverse circumstanc However, it suffers from the disadvantage of a low starting torqueConstruction of Induction Motor The three phase induction motor is a preferable type of motor It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable.

The rotor is of the squirrel-cage type and is under the influence of this moving field Consequently, a small starting torque is developed As soon as this torque starts to revolve the rotor, additional torque is produced by single-phase induction-motor actionrotor induction motor with extra resistance inserted into the rotor Because of the large rotor resistance, this motor has a pullout torque occurring at a high slip, and its starting torque is quite high A squirrel-cage motor with this type of rotor construction is called NEMAdesign class D.
