Rare earth permanent magnet materials are metallic And the [...]
Permanent Magnet Synchronous Motor vs AC Induction Motor Rare earth permanent magnet motor is a kind of permanent magnet motor that only appeared in the early 1970s. Due to the high magnetic energy product (BHmax) and high coercive force (especially high intrinsic coercive force Hcj) of rare earth permanent magnets, rare earth permanent magnet motors [...]
China's rare earth is stuck in the neck of permanent magnet motors, and foreign manufacturers are trying to get rid of "neodymium" dependence Rare earth permanent magnet motor is a kind of permanent magnet motor that appeared in the early 1970s. It has a series of advantages such as small size, light weight, high efficiency, [...]
What is the difference between permanent magnet synchronous motor and induction asynchronous motor? In this era when new energy vehicles are gradually emerging, the driving motor is as important to new energy vehicles as the engine is to fuel vehicles, because it not only determines the speed of vehicle startup, but also determines the acceleration [...]
Why is the permanent magnet synchronous motor with high integration, high power and low energy consumption the right choice Under the joint action of many factors, electric vehicles have become an unstoppable trend of transportation. There are more and more types of electric vehicles driving on the streets, and consumers' awareness of electric vehicles has [...]
Stator and rotor are the key components of permanent magnet synchronous motor The motors in new energy vehicles mainly include drive motors and micro motors. The drive motor can convert electrical energy into mechanical energy to provide power for electric vehicles according to the law of electromagnetic induction.

Axial Flux Motor Magnet, PM Axial Flux Motors Magnet, AXIAL FLUX ELECTRIC MOTOR MAGNETS, Axial and radial flux motors. As with other motor designs that include permanent magnets, PMAC axial flux motors exist. What is axial flux motor? An axial flux motor is different from conventional electric motors due to the different path of the [...]
Synchronous Generators Definition: The synchronous generator or alternator is an electrical machine which converts the mechanical power from a prime mover into an AC electrical power at a particular voltage and frequency. The synchronous motor always runs at the constant speed called synchronous speed. Synchronous Generators Working Principle of Synchronous Generator The synchronous [...]
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 [...]
