Problems solved by technology

Such a control device is formed on a substrate (printed circuit board) etc., and it is difficult to realize a stator molded motor for a motor incorporating such a printed circuit board
This is because a conductive connection is required between the coils inside the molded block and the printed circuit board (PCB), which is difficult to achieve
Even if such a connection is formed, its reliability is questionable
In addition, for the stator molded motor, due to the complicated assembly process, there is a problem that it is not easy to assemble, and the probability of defective products during the assembly process is high

Embodiment Construction

[0045] The structure of the motor of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] First, if figure 1 As shown, the motor of the present invention includes: a stator assembly 100 , a rotor assembly 300 and a PCB 200 .

[0047] That is, the above-mentioned rotor assembly 300 rotates relative to the stator assembly 100 . The PCB therein acts as a control to make the rotor assembly 300 rotate. The above-mentioned stator assembly 100 includes: a stator 110 and a molding part 130 . Wherein, the molding part may be formed of materials such as resin, and is preferably molded by bulk molding compound (Bulk Molding Compound, BMC).

[0048] Such as figure 2 As shown, the above-mentioned stator 110 includes: a stator core 111 , an insulator 112 and a stator coil 119 (hereinafter referred to as “coil”).

[0049] The above-mentioned stator core 111 is generally formed of laminated iron sheets, and although not shown in t...

Abstract

The invention discloses a motor comprising a stator assembly, a printed circuit board and an upper bracket. The stator assembly is integrally formed by a stator and a moulding part and provided with an opening part at the upper part; the printed circuit board is provided with an electrifying part at the top surface and mounted on the upper part of the stator assembly; and the upper bracket is combined with the stator assembly and encloses the upper opening part of the stator assembly. The motor is characterized in that an intensity reinforced rib is formed on the local top surface of the upper bracket. The motor is characterized that: a waterproof structure is formed between the moulding part and upper bracket. The motor comprises waterproof structure, is easy to manufacture, has higher efficiency and longer service life. Besides, the motor has the characteristics of miniaturized volume, easy installation and convenient use, and the denoising and vibration resisting performance of the motor are improved.

Description

technical field [0001] The invention relates to a motor, in particular to a motor that is easy to manufacture, has high efficiency and long service life, is small in size, easy to install and convenient to use. Background technique [0002] Generally, a motor refers to a device that rotates the rotor through the electromagnetic interaction between the stator and the rotor, and transmits the rotational force to the outside. Among them, the rotational force of the rotor is transmitted to the load through the rotating shaft to make it rotate. The stator generally includes a stator core and coils wound on the stator core. The stator core is insulated from the above-mentioned coils by an insulator or a winding shaft. [0003] However, at least a part of the stator and the rotor are provided in a frame that forms the appearance of the motor, and there is a problem that the coils may be damaged due to changes in the external environment or vibrations. In addition, there is also ...
