Synchronous Motor Operation & Speed Determinants

Sinotech    January 28, 2014

A synchronous motor is an AC motor whose shaft rotation is in sync with the supply current’s frequency as the motor runs at a steady state. Consequently, the integral number of AC cycles is the same as the rotation period. Synchronous Motor Operation Electromagnets on the stator of a synchronous motor create a magnetic field that rotates at the same time as the oscillations of the line current. The magnetic field also causes the rotor to turn in step and at the same rate. When the poly-phase supply excites the stator winding, a rotating magnetic field occurs within the motor….

Choosing Hazardous Duty Synchronous Motors & Stepper Motors

Sinotech    July 2, 2013

In the gear motor world, the two main types of motors are the AC synchronous motor and the DC stepper motor. Synchronous motors have a shaft that rotates at the same frequency as the supply current, so the supply current equals the number of AC cycles. The stepper motor is a BLDC motor whose full rotation is divided into an equal number of steps. The risk of hazards occurs when you use a constant-speed motor with a variable-frequency controller because it becomes potentially explosive. Synchronous Motor and Stepper Motor Hazards Explained The heat a synchronous or stepper motor produces when…
