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. It is mainly composed of stators, rotors, [...]
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. [...]
How linear motors work? In a traditional DC electric motor, a central core of tightly wrapped magnetic material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied. In an AC induction motor, electromagnets positioned around the edge 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 [...]
Hybrid Stepper Motor The hybrid stepper motor combines features of both the variable reluctance stepper and the permanent magnet stepper to produce a smaller step angle. The rotor is a cylindrical permanent magnet, magnetized along the axis with radial soft iron teeth (Figure below). The stator coils are wound on alternating poles with corresponding teeth. [...]
Brush DC Motor Basics Brush DC technology originates from a design based on an ironless rotor (self-supporting coil) combined with a precious metal or carbon copper commutation system and a rare earth magnet, ferrite or Alnico magnet. It offers distinct advantages for high-performance drive and servo systems: low friction, low starting voltage, absence of iron [...]
