Induction motor - Wikipedia 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. Massachusetts Institute of Technology - MIT OpenCourseWare Massachusetts Institute of Technology Department of Electrical Engineering and Computer Science 6.685 Electric Machinery Class Notes 8: Analytic Design Evaluation of Induction Machines c 2005 James L. Kirtley Jr. 1 Introduction Induction machines are perhaps the most widely used of all electric motors. They are generally
Are there any generalizations that can be made about the # rotor bars and # stator slots in an induction motor?For example I am reviewing two 4-pole motors evaluations now, both are same hp, same design, SF, duty, both have 48 stator slots, but one motor has 46 rotor bars and the other...
This paper proposes optimal design method of stator slot for three-phase cage induction motor fed by six-step inverter output voltage by using proposed analysis method. The finite-element method (FEM) on one phase band stator periodic condition is coupled with har- monic equivalent circuit. Induction motor - Wikipedia 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 of stator & rotor for Wound Induction Motor 6. Design of Stator Stator slots: in general two types of stator slots are employed in induction motors viz, open clots and semiclosed slots. Operating performance of the induction motors depends upon the shape of the slots and hence it is important to select suitable slot for the stator...

8. Winding Design: The winding used for induction motor stators are mainly double layer lap type winding with diamond shaped coils. Small motors with small number of slots and having large number of turns per phase may use single layer mush winding. The five phases of the winding are connected...
Why rotor slots is more than stator slots in induction … In an induction motor the rotor currents are induced by themagnetic field of the stator, and if the motor were to run atsynchronous speedBecause the motor is much simpler and easier to design when theelectrical power is supplied to the stator, while the rotor is ashort-circuited copper cage.

Abstract: The shape design of stator slot of 3-phase cage induction motors for iron loss reduction is presented. For optimum shape design, the sensitivity analysis by discrete approach is employed and the gradient projection method for nonlinear constraint problems is chosen for an optimization algorithm.
Cage induction motors are widely used in industries because of their rugged construction and low cost. The drawback with an induction motor isAir gap length in an induction motor is already very less; therefore it is not reduced below a certain level. There are three shapes of stator slots- parallel...

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 Stator of an induction motor consists of stator core and stator slots. Stator slots: in general two types of stator slots are employed in induction motors viz, open clots and semiclosed slots. Operating performance of the induction motors depends upon the shape of the slots and hence it is important to select suitable slot for the stator slots. 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].
