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]. Why are the slots on the rotor of an induction motor skewed ... Rotor of an Induction Motor skewed due to following reason… With the bar skewed,the amount of the bar cutting the field line grows continuously and the next bar starts cutting the field lines as the first finishes.Due to this,we get Uniform Torque. To run quietly by reducing the magnetic hum, reduce rotor locking tendency.

Because of the difference in field frequencies, eddy currents will be induced in the rotor bars. On the other hand, when running as an Induction Motor, slip speed will be an output of the analysis, depending on the load on the rotor.

Construction of Induction Motor - Electrical Edition Induction motor is the most commonly used machine in domestic purpose and industrial purpose.It is made up of a number of stampings, which are slotted to receive the windings. 3.The stamping is generally made up of silicon steel, which helps to reduce the hysteresis loss occurring in motor. Construction of Induction Motor - EEEGUIDE
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. It is also called asynchronous motor because it does not run at a synchronous speed.

CHAPTER 4 DESIGN AND DEVELOPMENT OF THREE WINDING Design of three phase three winding induction motor is affected by various constraints such as thermal limit, overload capacity and utility of stator slots. The energy conserving three stator winding induction motor is ideal to be used for low power operations due to the limitation in thermal insulation value. MAGNETIC NOISE IN INDUCTION MOTORS - … the field effects of stator-rotor slot combinations are the common causes for high magnetic noise in induction motors [3], [4], [5]. Finley [4] discussed various techniques to decrease the magnetic noise in electric motors. A good literature review on this topic could be found in [7].
