Do you know which two types of miniature DC planetary reduction motors fall into? Micro DC planetary deceleration motor is divided into brush planetary deceleration motor carbon brush deceleration motor and brushless planetary deceleration motor.
Brushless DC planetary deceleration motor is operated by carbon brush, and its life is limited. When the carbon brush is used up, its life is over. There are generally brush reduction motor life in the market about 1000H, of course, some only a few hundred hours of life.
Brushless DC planetary deceleration motor, compared with the carbon brush motor, has a long life, not controlled by the carbon brush, the life of at least 3000H. Because brushless reduction motor has long life, low noise, high torque, so the price is higher than brush reduction motor, even 2 times higher.
Characteristics of micro-DC planetary deceleration motor: compared with the same kind of ordinary physical gear box, it has smooth transmission, large bearing capacity, small space and large transmission ratio, especially the life. Compact size, beautiful appearance.
Planetary gear box is an important part widely used in mechanical transmission. When a pair of gears engage, due to the inevitable errors such as tooth pitch and tooth shape, there will be meshing impact and noise corresponding to gear meshing frequency in the operation process. Friction noise also occurs between tooth surfaces due to relative sliding. As the gear is the basic part of gearbox transmission, it is very necessary to reduce the noise of gearbox. Generally speaking, the causes of gear system noise mainly include the following aspects:
1. Gear design. Improper parameter selection, too little coincidence, improper or no modification of tooth profile, unreasonable structure of gear box, etc. In gear machining, the errors of base pitch and tooth shape are too large, the clearance of tooth side is too large, and the surface roughness is too large.
2. Gear system and gear box. Assembly eccentricity, low contact accuracy, poor parallelism of the shaft, shaft, bearing, bearing stiffness is insufficient, bearing rotary accuracy is not high and improper clearance.
3. Input torque from other aspects. Fluctuation of load torque, torsional vibration of shafting, balance of motor and other transmission pairs, etc.

Miniature dc planetary gear motor is widely used in office automation, intelligent household, production automation, medical apparatus and instruments, financial machinery, game consoles, and other fields, such as hollow shutter, smart toilet, automatic dryer, electric tools, automatic open window machine, automatic curtain, glass curtain wall, the bank ATM machine, automatic paper, paper machines and other automatic machines.
