Electrical Training

Motors and Control Circuits. Module No.SP2

This is the second module in the 'Skills Plus' series. It introduces motors, their principles of operation, and the circuits used to control and protect them, to those with a basic knowledge of electrics. Topics covered include single phase and three phase motors, D.C. motors, control circuits including relays, interlocks, contactors, overloads, and timers.
This module is targeted at crafts people, fitters, apprentices, technicians and new engineers who require a good working knowledge of electrical control of equipment with a view to basic faultfinding and modification of circuits.

LEARNING OUTCOMES

On completion of this module the student will;

  1. Understand the operation of single phase motors, three phase motors and dc motors.
  2. Be able to reverse the direction of a motor.
  3. Understand the difference between star and delta operation of three phase motors.
  4. Read and wire-up schematic diagrams, which include relays, timers, contactors and overloads.
  5. Be able to set and reset motor overloads.
  6. Fault find and modify motor control circuits.
  7. Test motors for faults and burnouts.
