Motor

Abstract

The invention discloses a motor comprising a stator assembly, a printed circuit board, a rotor assembly, an upper bracket, a lower bracket and a power supply splicing terminal. The stator assembly is integrally formed by a hollow stator iron core, a stator of an insulator with coils winded on the iron core and a moulding part surrounding the stator iron core and the insulator; the printed circuit board is mounted on the upper part of the stator assembly; the rotor assembly is rotatably arranged inside the stator assembly; the upper bracket and the lower bracket respectively enclose the upper part and the lower part of the stator assembly; the power supply splicing terminal is arranged on the insulator; and when the moulding part is formed, one end of the terminal exposes on the upper part of the moulding part and is electrically connected with the printed circuit board. The invention has the advantages that the motor is a stator moulded-type motor, and the printed circuit board is accurately combined with the stator assembly to prevent coils from being damaged; besides, the combining directions of the rotor assembly and the printed circuit board are different, thereby conflict therebetwwen is relieved. The motor is easy to manufacture and convenient to assemble, and can greatly improve the production efficiency.

Description

technical field [0001] The invention relates to a motor, in particular to a small motor with high efficiency, long life and convenient use. Background technique [0002] Generally, the motor is a device that rotates the motor through the electromagnetic interaction between the stator and the rotor, and transmits the rotational force to the outside; the rotational force of the rotor drives its load through the rotating shaft. [0003] In addition, the stator generally includes a stator core and a coil wound on the stator core; the stator core is insulated from the coil by an insulator or a winding shaft. [0004] In the above structure, at least part of the stator and the rotor are placed in the bracket forming the appearance of the motor, and the coils may be damaged due to changes or vibrations in the external environment. At the same time, the coil or stator core also has hidden dangers of leakage. [0005] In order to solve the above problems, it is generally adopted to...

Problems solved by technology

[0007] When this kind of control device is formed on the substrate (printed circuit board), for a motor with a printed circuit board inside the motor, there needs to be a wire connection between the coil located inside the molded block and the printed circuit board, which is difficult to realize. Stator molded motor

[0008] In addition, the stator molded motor is difficult to assemble due to many processes, and the probability of defective products will be high
