Technical Field

[0001] The utility model specifically relates to the technical field of motors, in particular to a silent motor. Background Art

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuits, it is represented by the letter M (D in older standards). Its primary function is to generate driving torque, serving as a power source for electrical appliances and various machines. A generator is represented by the letter G in circuits. Its primary function is to convert mechanical energy into electrical energy.

[0003] Traditional motors usually make noise when running, and the noise increases with the size of the motor. Especially for motors used in workshops and rooms, the noise generated is not easy to dissipate, which makes the staff nearby extremely uncomfortable. For this reason, we provide a silent motor. By setting an inner shell and an outer shell, and pasting shell sound insulation cotton on the inner shell and the outer shell, the sound inside is absorbed. The internal heat dissipation holes on the inner shell and the cavity between the inner shell and the outer shell can allow gas to circulate, which can reduce the heat dissipation inside, effectively compensating for the above problems.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] In the utility model, the shell sound insulation cotton pasted on the inner walls of the inner shell and the outer shell can absorb the generated noise, and the multiple internal heat dissipation holes on the inner shell and the cavity between the inner shell and the outer shell can facilitate the circulation of gas, thereby effectively dissipating heat while reducing noise, and the internal support frame plays a supporting role;

[0014] The utility model requires a bearing with a seat for fixing the drive shaft on the front shell, which is thicker than the rear shell and has a certain sound insulation effect. The rear sound insulation cotton on the rear shell can further absorb the noise generated, and the air holes facilitate the entry of gas.
