There are many advantages to planetary gear reduction motors. Among various products with high torque such as electronic locks and magic clips, what are the differences and advantages compared to cylindrical gear reduction motors?

1. Planetary reducers operate more smoothly, have stronger resistance to impact and vibration compared to cylindrical gear reducers. Due to the use of several planetary gears with the same structure, which are distributed around the sun gear, the forces between the planetary gears and the rotating arm can be balanced. Therefore, planetary reducers have strong impact resistance and reliable working performance.

2. The planetary gear reducer has a large transmission ratio, which can achieve the synthesis and decomposition of motion. As long as the appropriate transmission type and gear matching scheme are used, the planetary gear reducer can achieve a large transmission ratio, which can reach thousands. While achieving a large transmission ratio, the planetary gear reducer can maintain the advantages of compact structure, small volume, and light weight.

3. Planetary reducers are smaller in size, lighter in weight, and have a larger load capacity than cylindrical gear reducers. Planetary reducers can reasonably apply internal meshing teeth and have power splitting and coaxial transmission composed of various central wheels, making their structure very compact. Multiple planetary gears are evenly distributed on the sun gear to share the load together, reducing the load each gear bears and allowing the gear to adopt a smaller modulus. In addition, the structure fully utilizes the large internal meshing carrying energy and the tolerable volume of the internal gear ring itself, aiming to reduce the external dimensions of the planetary reducer, making it small in size, light in weight, and compact in structure.

4. The transmission efficiency of planetary gear reducers is higher than that of ordinary gear reducers. The efficiency of planetary gear reducers can reach up to 98%, while the efficiency of ordinary gear reducers is only about 80%. Due to the symmetry of the gear transmission of planetary reducers, they have uniformly distributed planetary gears, which balance the reaction force acting on the sun gear and the rotating arm, which can be beneficial for improving efficiency.
