Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a permanent magnet DC energized motor. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. From the perspective of energy structure, the current traditional motors can be divided into two categories: one is a motor driven by only one kind of electrical energy, and its energy structure is "one yuan", such as AC Motors, DC motors, reluctance motors, etc.; the other type is a motor driven by electric energy and permanent magnet energy, and its energy structure is "binary". Figure 1~2 , such as permanent magnet motors, permanent magnet synchronous motors, permanent magnet brushless DC motors, etc., because the binary motor increases the permanent magnet energy level from the structure, so the utilization rate of permanent magnet energy is improved, and its power saving rate is ordinary than that of the u...

[0002] A motor is a device that converts electrical energy into mechanical energy. From the perspective of energy structure, the current traditional motors can be divided into two categories: one is a motor driven by only one kind of electrical energy, and its energy structure is "one yuan", such as AC Motors, DC motors, reluctance motors, etc.; the other type is a motor driven by electric energy and permanent magnet energy, and its energy structure is "binary". Figure 1~2 , such as permanent magnet motors, permanent magnet synchronous motors, permanent magnet brushless DC motors, etc., because the binary motor increases the permanent magnet energy level from the structure, so the utilization rate of permanent magnet energy is improved, and its power saving rate is ordinary than that of the unitary motor 10-20% increase, but due to its structural limitations, there are certain deficiencies: 1. The two poles of the electric excitation core can only use one of the poles or one level to work

2. The N and S poles of the permanent magnet can only work on one pole surface or one level

3. The arrangement of permanent magnets lacks the magnetization effect, so the utilization rate is not high, the structure of the rotor armature is complex, the power consumption is high, and the temperature rises; in summary, the utilization rate of permanent magnet energy should be improved
