AC Motors Course #150

This is an instructor led, compentency based program designed for master level electricians. The course will teach electricians to understand the operation and maintenance of three phase motors.

    Learner Outcomes
  • The student will be able to associate the flow of current to the development of a magnetic field. Given a wire carrying a current in a magnetic field, the student will be able to predict the direction of motion.
  • The student will comprehend how a motor accelerates up to speed and be able to calculate a motors full load speed given its pole and % slip.
  • The student will be able to draw a physical diagramof a shading pole motor and dteremine the direction of motion.
  • The student will be able to draw a wiring diagram of a split phase, dula voltage motor. The student will be able to reverse the direction of a split phase motor.
  • The student will be able to compare starting torque of shading pole, split phase capacitor motors.
  • The student will be able to calcultate motor slip and synchronous speed of a 3 phase motor.
  • The student will be able to use the NEMA classification design letter to determine the proper starting torque of a motor.
  • Given log-log graph paper, the student will draw fuse curves to protect a motor.
  • The student will acquire knowledge of proper motor maintenance for motors and develop a test plan.
