Shaded pole single phase induction motor pdf
list the common types of singlephase induction motors. north pole and one south pole, it is a 2pole motor. Unit 16 Electric Motors 379. N Phase B Phase C 320 Unit 16 Electric Motors N Phase C Figure 165 The direction of rotation of the magneticShadedpole. SinglePhase Motor Starting In addition to the run or main winding, all induction singlephase motors are equipped with an auxiliary or start winding in the stator. The auxiliary or start winding overlaps the main or run winding. This provides the revolving field necessary to turn the shaded pole single phase induction motor pdf
Single Phase Induction Motor The singlephase induction machine is the most frequently used motor for refrigerators, washing machines, clocks, drills, compressors, pumps, and so forth. The singlephase motor stator has a laminated iron core with two windings arranged perpendicularly.
Chapter 7 SinglePhase Motors 7. 1 Introduction Singlephase induction motors are usually twopole or fourpole, rated at 2 hp or less, while slower and larger motor can be A singlephase induction motor is not self starting but requires some starting means. Shaded Pole Single Phase Induction Motors The stator of the shaded pole single phase induction motor has salient or projected poles. These poles are shaded by copper band or ring which is inductive in nature. The poles are divided into two unequal halves. The smaller portion carries the copper band and is called as shaded portion of the pole. shaded pole single phase induction motor pdf The shaded pole motor is simply a selfstarting singlephase induction motor whose one of the pole is shaded by the copper ring. The copper ring is also called the shaded ring. This copper ring act as a secondary winding for the motor.
May 16, 2008 speed control of shaded pole induction AC motor. Discussion in 'Electronic Design' started by [email protected, Apr 29, It is possible to rewind a shaded pole single phase motor to be three phase. I did this with a 140 HP fan motor, and I used# 14 AWG wire so that Phase control Shaded pole motor. shaded pole single phase induction motor pdf The. stator of the shaded pole single phase induction motor has salient or projected poles. These poles are shaded by copper band or ring which is inductive in nature. The poles are divided into two unequal halves. The smaller portion carries the copper band and is called as shaded portion of the pole. A Shaded Pole motor is an AC single phase induction motor. The auxiliary winding, which is composed of a copper ring, is called a shading coil. The current in this coil delay the phase of magnetic flux in that part of the pole in order to provide a rotating magnetic field. ShadedPole SInglePhase Motors Like any other motors the shaded pole induction motor also consists of a stator and rotor. The stator is of salient pole type and the rotor is of squirrel cage type. The poles of shaded pole induction motor consist of slots, which are Shaded pole motor is one of the types of single phase induction motors, which are used for producing a rotating stator flux in order to make the single phase induction motor a self starting one. Let us discuss the constructional details, diagrams and working of shaded pole motors in detail.Rating: 4.40 / Views: 670
