Sinotech Motors
Induction Motorsthere is no difference between rotor speed and rotating field speed, so no voltage is induced in the rotor bars, hence no torque is developed. Therefore, when running, the rotor must rotate slower than the magnetic field. The rotor speed is just slow enough to cause the proper amount of rotor current to flow, so that the resulting torque is sufficient to overcome windage and friction losses, and drive the load. Polyphase motors. NEMA classifies polyphase induction motors according to locked rotor torque... (read more)Browse AC Motors Datasheets for Sinotech Motors -
Sinotech Motors
Synchronous Motorsor polyphase, cannot start without being driven, or having their rotor connected in the form of a self-starting circuit. Since the field is rotating at synchronous speed, the motor must be accelerated before it can pull into synchronism. Accelerating from zero rpm requires slip until synchronism is reached. Therefore, separate starting means must be employed. In self-starting designs, fractional horsepower motors use methods common to induction motors (split phase, capacitor-start, and shaded...

Custom AC MotorsSinotech's AC motors are engineered in the U.S. and manufactured offshore for very competitive pricing. Basics of AC Motor Design Engineering. Asynchronous motors and synchronous motors are the two main categories of ac motors. The ac induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary. The primary winding (stator) is connected to the power source and the shorted secondary (rotor) carries the induced secondary current. Torque...

ARC Systems, Inc.
Induction MotorsThe 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. -
