INDUSTRIAL CONTROL HANDBOOK - 2.7 THEORY OF OPERATION OF ELECTRIC MOTORS

All electric motors work through the interaction of electric current, magnetic fields, and motion or torque. Three principles of operation can he isolated to define the operation of motors in simple terms:
  1. Opposite magnetic poles attract each other.
  2. A current moving through a wire across a magnetic field will cause a force to be exerted on the wire. Most DC motors operate on this principle. Their speed can be controlled by altering either the amount of current flowing through the wiring in the armature.
  3. When a conductor moves across a magnetic field, a voltage is produced in it that will cause a current to flow (if the conductor is part of a closed circuit).
