AC REPULSION MOTOR





Description:

 

AC REPULSION MOTOR:

Introduction:

  • AC Repulsion motors belong to the family of Single phase motors with the difference that they have wound rotor, commutator & brush arrangement resembling dc motors. But the operation is same as single phase motors & the brush arrangement is provided for reversal of speed of motor.
  • This Model is the Industrial/Educational model suitable for demonstrating to students the complete knows of the Basics, Components, Starting methods, Wear & Tear & Maintenance of these motors packaged in small rating.
  • Students can make connections of their own with the help of the terminations provided for study of features viz Starting methods, Speed-Torque, Effect of Change of Brush angle with rocker, Effect of reduced voltage , Blocked rotor test.

 

Technical Specifications:

  • Power ratings available            : 350W / 750W / 1KW /1.5 KW
  • Voltage Input                         : 230V AC, 50 Hz
  • RPM                                       : 1440 / 2880 RPM,
  • Single / Double shaft extension, SPDP, IP23, IC01, B3, Class-B, S1, Solid yoke.

 

LIST OF EXPERIMENTS POSSIBLE

  • Starting by DOL Starter
  • Starting by reduced voltage starter.
  • Load test & No load test of machine
  • Speed-Torque Analysis
  • Change in speed with Brush angle change
  • Zero speed point with voltage applied
  • Reversal of speed with brush angle.
  • Efficiency Analysis
  • Blocked rotor test
  • Cold Resistance & Hot Resistance
  • Motor Operation parameters
  • Basic Overhauling Know how.
