Encyclopedia of Permanent Magnet DC Motor
The permanent magnet brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product.
Permanent magnet brushless DC motor is a DC motor with one or more permanent magnets to establish a magnetic field. Its performance is similar to that of other excitation DC motors with constant excitation current. It can be easily adjusted by changing the armature voltage. Compared with single-excitation DC motors, it has the advantages of small size, high efficiency, simple structure, and small amount of copper. It is the main type of low-power DC motors.
