This unit provides the foundational knowledge for 3 phase induction motor understanding. Students will be introduced to the fundamentals of electric motor construction, motor speeds, and the ability to dismantle and assemble a 3 phase squirrel cage motor.

At the completion of the unit, students will develop skills in electric motor construction, design and the circuit analysis for a rotating magnetic field.

The topics covered in this course include:

  • Motor construction and design
  • Understanding rotating magnetic fields
  • Construction and design of motor starter poles and speeds
  • Connection of multi-voltage motors
  • Understanding of international motor voltages
  • Motor direction reversing
  • Completing motor testing and commissioning data


On successful completion of this unit, student will be able to:

  • Dismantle and reassemble a 3 phase electric motor
  • Connect a 3 phase motor in 415 V stud connection
  • Connect a 3 phase motor in 220 V star & 415 V delta
  • Test an electric motor for its correct performance requirements
  • Document and commission a 3 phase motor, at rest, and under load conditions
