The motor is divided into rotating armature type and rotating magnetic pole type. The one with the magnet on the stator is called rotating armature type. This type of motor generally requires a commutator and brushes. Due to the wear of the commutator and brushes, the service life is not as long as that of the rotating magnetic pole type, but the structure is simple and the production cost is low. Rotating magnetic pole type is also called brushless motor. The structure is relatively complex, but it is very reliable and difficult to damage. It is used in places where requirements are higher.
It can produce electricity. . Whether the magnet is placed tangentially or radially, take care. Use NdFeB magnets. Typically, permanent magnet generators have several pairs of poles and the stator is essentially made of fractional slot windings. If you change it toWith a motor rotor without changing the stator, your resistance distance will be very large.
