In the induction motor design, the rotor slots are purposely made with a slight skew arrangement.For industrial and mining applications, 3-phase AC induction motors are the prime movers for the vast majority of machines. AC Motors | Machine Design AC Motors. Pull-in torque of a synchronous motor is the torque that it develops when pulling its connected inertia load into synchronism upon application of excitation. Pull-in torque is developed during transition from slip speed to synchronous speed, as the motor changes from induction to synchronous operation. 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 - Magnetic noise levels can be reduced by adjusting various motor design parameters such as stator-rotor slot dimension and number. By modifying the stator slot size, the resonant frequencies of the core and tooth will change. For instance, a reduction in slot height will increase the stator tooth resonant frequency.


Induction Motors Notes - Design of Induction Motors ... to design an induction motor for best power factor unless specified. ... However the slot width will be varying from top of the slot to Traditional Design of Cage Rotor Induction Motors

The Induction motors are the most widely used type of motor in the industry. Thus, induction motor design and control is of great importance. The effects of variation of the rotor slot area which is one of the most importance design parameters of the motor performance were examined. Change of the rotor slot area was examined in two ways.

Design and Development of Three Stator Winding Induction … 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]. Induction Motors Notes - For the normal design of induction motors the calculated diameter of the motor should be such that the peripheral speed must be below 30 m/s. In case of specially designed rotor the peripheral speed can be 60 m/s. Stator of an induction motor consists of stator core and stator slots. Induction Motor Design (3-Phase)
