RS-550/555A

We now produce a complete range of gear types.

According to gear structure: straight teeth, helical gear, bevel gear, worm gear, worm gear;

Accroding to gear material: plastic teeth, metal teeth (copper, stainless steel, powder metallurgy).

Our motor noise control is at the leading level in the industry;

Usually, we define the noise level of the motor (in dB) based on the background noise and the measurement distance.

Noise is divided into two categories: mechanical noise and electrical noise. Mechanical noise is mainly related to the structure of the motor itself and the running speed of the motor (generally speaking, the faster the speed, the greater the noise), while electrical noise mainly comes from the sparks generated by the friction between the brush and the commutator.

Currently, there is no noiseless motor in the motor industry. We will improve the design to make the noise of the motor reach the level required by customers.

We usually use two types of brushes: metal brushes and carbon brushes. The choice of brush depends on several factors, including the speed, current carrying capacity, and life expectancy of the motor. For smaller motors, we usually choose metal brushes; For larger motors, we tend to choose carbon brushes. Compared to metal brushes, carbon brushes have a longer service life and can significantly reduce the wear on the commutator.

Kinmore mainly produces DC motors, including brushed DC motors, brushless DC motors, Gear motors, etc.

Compared with the brushed motor, the brushless motor has the advantages of high efficiency, long life, low noise, and various control methods.
