Cost effective permanent magnet brushless DC deceleration/speed reducing motor principle and application
Permanent magnet DC motor is a DC motor with the permanent magnet to set up a magnetic field. Permanent magnet DC motor can be divided into permanent magnet brushless DC motor and permanent magnet DC motor with brush. Permanent magnet brushless DC motor is a DC motor with one or multiple permanent magnets to set up a magnetic field, whose property is similar with other-excited DC motor of constant excitation current. Its speed can be easily adjusted by changing the armature voltage. Permanent magnet brushless DC motor featuring small volume, high efficiency, simple structure and less use amount of copper, etc. is one of the main types of small-power DC motor.
DC deceleration motor or gear motor is equipped with a supporting gear reducer on the basis of the ordinary DC motor. The role of the gear reducer is to provide low speed with a large torque, which has greatly increased the utilization rate of the DC motor in the automation industry.
Permanent magnet DC speed reducing motor is widely used in appliances and all kinds of portable electronic devices, such as all kinds of toy, electric massager, recorder, VCD and record player, which is also extensively applied in the industries like motorcycle, automobile, electric bicycle, battery car, hand drier, machinery, shipbuilding and aviation, etc. and other industries. It also has a widespread use in some high-tech products such as mobile phone, camera, video recorder, copier, cash-counting machine, money bidder and precision machine tool, etc.
