According to 2019-2025 Current Situation Analysis and Prospect Research Report of China’s Motor Industry issued by China Industrial Research Network, motor manufacturers in China coexisted in various types, such as foreign-owned enterprise, joint enterprise, state-owned enterprise, joint-stock enterprise, and individual enterprise, whose annual output value develops from several million hundred RMB to millions of yuan. In fact, other countries around the world are also experiencing a rapid development of planetary gear motor.
A product category that the motor industry involved includes gear motor, cycloidal pinwheel motor, harmonic drive, and worm gear motor, etc. Now let me introduce the development and prospect of planetary gear motor.
Planetary Motor Achieved Mechatronics
Generally speaking, the micro machine requires a compact gear drive device consisting of a micro motor and planetary gearheads for deceleration and transmission. The features of the gear drive device with mechatronics are that the output shaft and the input shaft are coaxial and the shaft of the motor is compactly connected with its load. In structure, the shaft of the motor can be connected with the output shaft of the planetary gear motor. In other words, both the shaft of the motor and the gear shaft of the sun wheel “a” are connected on the same main shaft. The output shaft of the planetary gear motor (the shaft that connected with internal gear “e”) is the output shaft of the combination, so the built-in gear drive device is combined with motor and planetary gear reducer, which means the output shaft can connect to the working machine directly. In order to make this kind of micro machine practical, both compact size and functionality of planetary gear motors are needed.
The Frequently-Used Micro Planetary Gear Motor
The Applications of Planetary Gear Motor
The planetary gear motor can be used for any application requiring high output and torque in a compact, low-noise design. It is adopted in many fields mainly including intelligent automobile, consumer electronics, medical technology, intelligent robots, communication equipment, medical electronics, automatic industry device, smart home and so on.
Lubrication of Gear Motor
The lubrication of the gear motor is important in the transmission of the micro planetary gear motor. According to relative literature, in general, as for the gear motor that transmits drive force, the smaller diameter of the main shaft is, the greater proportion of friction torque in total power loss covers. But measuring small friction torque accurately is not easy to achieve in the micro machine. It’s calculated that the loss proportion of friction torque of micro planetary gear motor in total power loss will be increased. Therefore, at present, people are conducting researches on the lubrication of micro planetary gear motor in order to promote the performance of micro planetary gear motor.
The applications of gear motor can fasten the development of electric power, construction machinery, construction materials, and energy industry. With the urging importance of the machinery manufacturing industry, the demand for gear motor of enterprises increases. In a word, the production of gear motor will enter a competitive stage to meet the needs of the market.
