What are The Advantages of Permanent Magnet Synchronous Motors? 1. The permanent magnet synchronous motor has simple structure, small size, lightweight, low loss, high efficiency, and easy to achieve secondary energy efficiency and primary energy efficiency motors. 2. Compared with the DC motor, it has no shortcomings such as the commutator and brushes of the [...]
Synchronous Traction Motor Permanent Magnets Using high-performance rare earth permanent magnet materials, no carbon brushes, permanent magnet synchronous gearless traction machine can drive efficiency up to 90%. It effectively improves the energy efficiency with energy saving, environmental protection, low speed and high torque characteristics. Gearless traction machine can be dividedinto the inner rotor and outer [...]
Synchronous Reluctance Motor Breakthrough Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages. The new motors use an innovative rotor design that eliminates the slip losses associated with induction motors while offering the benefits of permanent magnet operation. [...]
Magnet Rotors, or permanent magnet rotor is the non stationary part of a motor. The rotor is the moving part in an electric motor, generator and more. Magnetic rotors are designed with multiple poles. Each pole alternates in polarity (north & south). Opposite poles rotate about a central point or axis (basically, a shaft is [...]
Synchronous Motor Working Principle The stator and the rotor are the two main parts of the synchronous motor. The stator is the stationary part of the motor and rotor is their rotating part. The stator is excited by the three-phase supply, and the rotor is excited by the DC supply. The term excitation means the [...]
