ABB magnet free synchronous reluctance (SynRM) motors combine the advantages of permanent magnet technology together with the simplicity and service-friendliness of an induction platform. Together with a drive, the motor offers new choices for energy efficiency and compactness. Features
With synchronous motor technology, speed is directly proportional to AC input frequency – for example, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed can be varied by varying the frequency, although most applications simply use gearing or a belt- or chain-drive system to achieve the desired load speed.

Jul 30, 2018· Now coming to the point how synchronous motors are started. At first the synchronous motors are started as a normal induction motors, the rotor of the motor is not given DC supply, when the motor reaches the rotor and pull in takes place, which is discussed later. Another method of starting the synchronous motor drives is by
Do you know that the Synchronous motors work on a unique theory of operation unlike normal motors? Read here to Know about its working principle and starting procedures. Also know the applications of these motors in different fields. Appreciate the comparison between a normal Induction motor & a Synchronous motor. Read to know about the surging/hunting of these motors.
The synchronous motor and induction motor are the most widely used types of AC motor. The difference between the two types is that the synchronous motor rotates at a rate locked to the line frequency since it does not rely on current induction to produce the rotor's magnetic field.

Three phase, 4-pole synchronous motor Small Multi-Phase Synchronous Motors. Small multi-phase synchronous motors may be started by ramping the drive frequency from zero to the final running frequency. The multi-phase drive signals are generated by electronic circuits and will be square waves in all but the most demanding applications.
synchronous motor was chosen. This article will describe the characteristics of the syn-chronous motor, field application, and the excitation sys-tem selected for this application. For Lion Oil, the new synchronous motor would be rated for 5,000 hp, 13,800 Vac, operating at 327 r/min. Construction of a Synchronous Motor
Permanent magnet motors MUST operate with a drive. AC induction motors can be used without a VFD to drive a pump or fan, but are often installed with variable frequency drives (VFD) in pump systems or fan systems in an effort to improve system efficiency. Permanent magnet synchronous motors require a drive to operate. PMSMs cannot run without a ...

Synchronous motors require additional starting mechanism to initially rotate the rotor near to the synchronous speed. No starting mechanism is required in induction motors. The power factor of a synchronous motor can be adjusted to lagging, unity or leading by varying the excitation, whereas, an induction motor always runs at lagging power factor.
