Motor

Abstract

The invention discloses a motor comprising a stator assembly, an opening part, a bracket and resins. The stator assembly is integrally formed by a stator and a moulding part surrounding a stator iron core and an insulator; the opening part is communicated with outside of the stator assembly; the opening part is connected with the upper part of the moulding part through a plane part; the outside diameter of the bracket is less than the inside diameter of the outside inner wall; a tail end along a radius direction is mounted on the plane part and keeps a certain gap with the outside inner wall to enclose the opening part; and the resins are coated in the gap. 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; the bracket and the moulding part are combined with each other more firmly via mechanical and chemical combination so as to prevent the bracket from being separated as a result of vibration during the operation process of the motor and avoid electric leakage caused by water penetration to the utmost extent. The motor is easy to manufacture and convenient to assemble, thereby greatly improving 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
