Permanent magnet direct current motors
This is a synchronous magnetic motor that places permanent magnets on the stator and uses an electromagnet with its coil wound on a soft magnetic core as the rotor. The rotational force is obtained between the permanent magnets of the stator and the electromagnetic induction produced on the rotor by the current flowing while the brush magnet poles switch. This is the most popular type of motor using magnets and a large number are in use. The structure is simple and sturdy and the price is reasonable, so they are easy to use. In general, ferrite magnets are used for stator magnets, but in recent high-performance type motors, rare earth magnets have been coming into use.
