Slot design of induction motor

By Publisher

The efficiency of an induction motor is determined by intrinsic losses that can be reduced only by changes in motor design.

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]. This paper presents a theoretical model for the prediction Induction Motor Design (3-Phase) DESIGN OF STATOR: Stator and rotor with semi-closed slots (1 ) Shapes of stator slots: May be (i ) Open Slot: Used for Synchronous M/Cs (i i) Partially Closed Slot: Used for Induction M/Cs (2 ) No of Stator Slots S1: Two approaches a. Slot pitch 1 1 15 20 S D sg mm So 1 1 sg D S For 3-Phase IM having P-poles S1 3q1P Where AN887, AC Induction Motor Fundamentals • Single-phase induction motor • Three-phase induction motor Single-Phase Induction Motor There are probably more single-phase AC induction motors in use today than the total of all the other types put together. It is logical that the least expensive, low-est maintenance type motor should be used most often. Design and characterization of an induction motor for ...

Optimal stator slot design of inverter-fed induction motor ...

Performance optimization design and analysis of bearingless ... Fig. 2 shows the model of the BI motor stator slot with a magnetic wedge, where the wedge-shaped design is conducted to homogenate the gap discontinuities in the existence of the slot and make the structure easier. In practice, In order to obtain each workpiece of the motor, magnetic material made of magnetic wedge can be used in different plates. Induction Motors - Dr. Jivraj Mehta Institute of Technology ...

Oct 12, 2017 · Design Of Stator & Rotor slot 3 Phase Wound Motor Subject : Design of AC Machines 2. Three-Phase Wound-Rotor Induction Motor CONSTRUCTION A three-phase, wound-rotor induction motor consists of a stator core with a three-phase winding, a wound rotor with slip rings, brushes and brush holders, and two end shields to house the bearings that

Most AC motors are induction motors. Induction motors are favored due to their ruggedness and simplicity. In fact, 90% of industrial motors are induction motors. Nikola Tesla conceived the basic principals of the polyphase induction motor in 1883, and had a half horsepower (400 watt) model by 1888 ...
