Additional Info

• 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 DC power supply, through a DPDT crossover switch, both to the field coils, and to the armature coils through one of the two commutators.

  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; turn off the power supply when you are through.
