Induction Motor Interview Questions & Answers Instrumentation… In the induction motor design, the rotor slots are purposely made with a slight skew arrangement. It will not be parallel to the shaft.This problem can be prevented by proper choice of stator and rotor slots and also by skewing the rotor slots by one slot pitch. [UPDATED] Induction Motor Questions In the induction motor design, the rotor slots are purposely made with a slight skew arrangement. It will not be parallel to the shaft.The basic difference between an induction motor and a synchronous AC motor is that in the latter a current is supplied onto the rotor.
Stator slots in Induction Motor: For smaller machines up to 20 kW, 600 V and diameter less than 40 cm, semi-closed slots are used.Hence conductors per stator slot = Z ss = 6 T s / S s. Rotor design of Induction Motor: Air gap length depends on: (i) Power factor
Chapter 8 Three Phase Induction Motor 8.1 Introduction Squirrel cage induction motor is used in lathes, drilling machine, fan, blower printing machines etc. 8.2.2.2 Wound rotor. Slip ring or wound three phase induction motor : In this type of three phase induction motor the rotor is wound for the same number of poles as that of stator but it has less Electric Machine Design Course - IEEE New design only of simple salient rotor seems the only major task? Can a motor made up of flux barriers and flux carriers be designed with sufficient mechanical integrity for rail duty? Can the rotor saliency ratio be high enough to match of exceed the torque density and power factor of the Asynchronous machine?? Design of a Three Phase Squirrel Cage Induction Motor for ... Air gap length is a major part of induction motor design. The air gap length is given by l g 1 .6 D 0 . 25 mm . (5) where, l g is air - gap length 3.Design Methodology The design process of induction motor is an iterative process. The machine designer first assumes the efficiency and power factor at the rated condition.
In some induction motors, what is called the ‘deep bar’ effect, or distribution of rotor currents due to eddy currents, is taken advantage of.It tapers toward the rotor surface. Fig. 3 shows the real and reactive parts of the impedance of the slot designed for aluminum with two different materials...
