i need the whole setup including the speed control position control as well as the torque control and brakingCWatters said:"Permanent magnet motors" can be tiny (used as vibrators in pagers) to real monsters. Speeds from 0 to >50,000 rpm. What sort of motors are you interested in?
What's the application? Do you just need to control the speed or position as well? Regenerative braking?
A permanent magnet motor drive train is a type of electric motor that uses permanent magnets to create a magnetic field instead of electromagnets. It is commonly used in various industries, including transportation, aerospace, and renewable energy.
The permanent magnets in the motor are fixed to the rotor, which is the rotating part of the motor. When electricity is passed through the stator, which is the stationary part of the motor, it creates a magnetic field that interacts with the magnets on the rotor, causing it to rotate and generate mechanical energy.
There are several advantages of using a permanent magnet motor drive train, including high efficiency, compact size, and lower maintenance requirements. They also have a higher power-to-weight ratio and can operate at higher speeds compared to traditional motors.
One limitation of permanent magnet motor drive trains is their higher initial cost compared to other types of motors. They also require rare-earth materials, which can be expensive and difficult to source. Additionally, their performance may be affected by high temperatures, and they may not be suitable for high torque applications.
Unlike traditional motors that use electromagnets, a permanent magnet motor drive train does not require a continuous supply of electricity to maintain the magnetic field. This makes it more energy-efficient and reduces the risk of power outages. It also has a simpler design, which results in lower maintenance requirements and a longer lifespan.
