This work is introducing the designing of new three phase squirrel cage induction motor with an objective of getting good efficiency. A motor rating of 10 horse power, 415 volts with 1440 rpm and 4-pole is selected for design problem and an equivalent circuit model is developed to find out the various Induction Motors Notes - ssmengg.edu.in
Induction Motor Design (3-Phase)
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. Design and Development of Three Stator Winding Induction Motor Design and Development of Three Stator 343 power consumed due to eddy currents, copper losses and poor power factor are considerably reduced [11]. The efficiency of an induction motors ranges between 0.75 and 22 kW can be improved by means of die cast copper instead of aluminium cage rotor with premium steel core [12].
