Permanent Magnet Rotor for Motors Permanent magnet rotor is the rotary part of a motor. The rotor is the moving part in an electric motor or generator. Magnetic rotors are designed with multiple poles. Each pole alternates in polarity (north & south). Opposite poles rotate around axis or a central point. Generally, there is a shaft located in the middle). NSE can design and supply most of the rotors for our customers. We can make sure that the designed rotor will be perfectly used in our customer application. We can supply whole rotor solution or magnets to be used on the magnetic rotor. Magnetic Rotor Usage Magnetic rotors are primary used in electric motors, electric generators and wind turbines, which are usually for air conditioners, washing machines, refrigerators, power tools, servos, robots, compressors, automotive electronic components etc.
