Planetary gear motor components

The planetary gear motor is composed of a permanent magnet rotor, a multipole winding stator and a position sensor. The position sensor converts the current of the stator winding in the corresponding order according to the change of the rotor position. The operating voltage of the stator winding is provided by the electronic switching circuit controlled by the position sensor output. The planetary gear motor is generally driven by L298N, which can generally drive two motors at the same time, and two L298N can be used if the drive is not enough. The internal principle is H-bridge differential amplification. It is a two-phase and four-phase motor driver, that is, a high-voltage and high-current dual full-bridge driver containing two H Bridges, receiving standard TTL logic level signals, can drive 46V, 2A below the motor.

The above mainly introduces the structure of the planetary gear motor, and has a simple understanding of its working principle.
