A Permanent Magnet rotor is a type of rotor used in electric motors and generators. It is made up of a series of cylindrical magnets that are made from a type of ceramic material called ferrite. Ferrite magnets are known for their high resistance to demagnetization and their ability to maintain their magnetic properties even at high temperatures. Ferrite magnet rotors are commonly used in small electric motors and generators, such as those found in household appliances, toys, and power tools.
Magnetized and unmagnetized refer to the state of an object's magnetic field. Here are some applications of both:
3. Electric motors: Unmagnetized materials are used in electric motors to convert electrical energy into mechanical energy.
