K4-24: AC/DC MOTOR

ID Code: K4-24
Purpose: Demonstrate the construction and the operation of AC and DC motors.
Description: This setup can be used to create either an AC or a DC motor. Connect 8 volt power supply both to the field coils and to the armature coils through a commutator. A DC motor uses the split ring commutator. Turn on the power supply and start with a small push. Reversing the polarity of the power supply reverses the direction of the motor. The armature voltage can be seen on the meter. An AC motor uses the double-ring commutator. Reversing the switch twice per rotation of the coil mimics an AC power source. NOTE: Please avoid destruction of the coils by turning off the power supply when you are through.
