An ac motor uses alternating current in other words the direction of current flow changes periodically. Some dc electric motor information below schematic wiring diagram for dc electric motor connections.

Ac electric motor diagram. In all cases if youre unsure about how the motor should be connected consult an expert as incorrectly wiring a motor can lead to a shocking hazard or injury. In the case of common ac that is used throughout most of the united states the current flow changes direction 120 times every second. But if the manual cannot be found the job becomes tougher. An ac motor is an electric motor driven by an alternating current ac. The magnetic field comes from the stator which is a permanent magnet while you feed the electric power to the. Electric motor nema c and j face mounting dimensions chart.
An ac motor converts electric energy into mechanical energy. Wiring an ac electric motor is not particularly difficult if the manufacturers manual is available. Ac motors are at the heart of the electrical consumption in the world because they do so much and with very little human intervention. An electric motor dimension chart depicting the standard frame sizes of electric motors. An ac alternating current motor is an electromechanical device that converts electrical energy into mechanical movement through the use of electromagnetism and the changing of the frequency and voltages produced by the utility company or motor controller. The ac motor commonly consists of two basic parts an outside stator having coils supplied with alternating current to produce a rotating magnetic field and an inside rotor attached to the output shaft producing a second rotating magnetic field.
I found this information about motor mounting dimensions in the same book. In a dc motor the magnet and its magnetic field is fixed in place and forms the outside static part of the motor the stator while a coil of wire carrying the electric current forms the rotating part of the motor the rotor. The rotor magnetic field may be produced by permanent magnets reluctance.
