. Since the electric motor is being used as a timer, it must run at a constant speed. Ac and dc electric motors can be used as timing motors. Dc electric timing motors are used for portable applications, or where high acceleration and low speed variations are required. These electric motors offer advantages, which include starting torque as high as ten times running torque, efficiency from 50 to 70%, and relatively easy speed control. But some form of speed governor, either mechanical... (read more)Browse AC Motors Datasheets for Sinotech Motors

The induction motor is the most commonly used type of ac motor. It's simple, rugged construction costs relatively little to manufacture. The induction motor has a rotor that is not connected to an external source of voltage. The induction motor derives its name from the fact that ac voltages are induced in the rotor circuit by the rotating magnetic field of the stator. ARC's complete lines of AC Induction Motors are manufactured using a squirrel cage rotor utilizing both aluminum and copper... (read more)Browse AC Motors Datasheets for ARC Systems, Inc.
