Know something about planetary gear motors

It is known that planetary gear motors widely used in treadmills and actuators. .planetary gear motor is generally through the motor. Look at the general inertia of the motor has a value Planetary gear motor can be divided into the following categories: servo planetary gearbox provides a cost-effective, widely used, economical, long life, etc. The advantage of planetary gear motor structure is compact, backlash and high precision, long service life. The rated output torque can do great. But the price is slightly more expensive
