PURPOSE: To demonstrate the concept of a synchronous motor.
DESCRIPTION: The power supply, operating at about 12 volts, is connected in parallel to the field coils and to the armature coils through the double-ring comutator. The current reversing switch can be used with either coil. Reverse the current twice per rotation as the device operates.
