Small reduction motor is the integration of micro motor, gear reducer and planetary reducer. According to the specifications and types of micromotor, structural characteristics of reducer, diameter specifications and output power size, it can be divided into different models, specifications and scope of application. The basic concept of the small reduction motor is to reduce the output transmission ratio of the micro motor based on the multi-level transmission gear, and to increase the output torque of the reducer according to the commodity regulations. When the small reduction motor outputs the input reducer, the transmission gear of the transmission system rotates. In addition, it promotes the transmission gear to complete the function of increasing force and reducing speed. The larger the equal ratio series of the transmission gear of the transmission system, the slower the output speed ratio and the higher the torque. Generally speaking, the leading role of the small reduction motor is as follows: (1) reduce the speed ratio: the speed ratio of the small reduction motor is determined according to the required speed ratio of the reducer, that is, the output speed ratio;

(2) Increase torque: under the same output power specification, the torque increases when the output transmission ratio is slow, and decreases when the transmission ratio is fast.

(3) Change the direction of the transmission device: such as reverse, vertical transmission. Small reducer helical gear motor can ensure the output power of a few tenths of a watt, with the advantages of small size, light weight and low noise. They are widely used in smart home system software, medical equipment, car drivers, intelligent robot products, electrical products, personal care and other commodities.

(1) Smart home system software: automatic curtain, intelligent sweeper, intelligent trash can, electronic control lock, shutter, intelligent toilet, etc. All of them are small reduction motors;

(2) Intelligent robot products: small gear reducer classification motor is suitable for all intelligent robot products, whether it is robot courses or interactive intelligent robots can be used;

(3) Medical equipment: infusion pump, ablation surgery linear fiber laser cutting stapler, self coagulation knife reducer motor and other mechanical equipment;

(4) Car controller: small reduction motor to drive car boot, electric window, car wiper, rear-view mirror adjustment, car skylight, electronic parking, etc.
