(Summary description)Because the DC gear motor is very different from the DC motor in structure. Therefore, the direction of rotation cannot be changed by changing the polarity of the power supply, and the rotation direction can only be changed by changing the relative relationship between the magnetic potential of the stator winding and the magnetic field of the rotor.

Information
1. Forward and reverse
 
Because the DC gear motor is very different from the DC motor in structure. Therefore, the direction of rotation cannot be changed by changing the polarity of the power supply, and the rotation direction can only be changed by changing the relative relationship between the magnetic potential of the stator winding and the magnetic field of the rotor.
 
 
2. Emblem control
 
The DC gear motor is produced and developed with the digital control technology, so it is the main control method to realize the digital control of the DC gear motor with a microcomputer.
 
3. Speed regulation
 
The speed regulation of the DC geared motor can be achieved by changing the magnitude of the voltage. There are two commonly used methods: one is to keep the on-time of each phase unchanged. The speed regulation is realized by changing the magnitude of the voltage amplitude applied to the coil when each phase is turned on.
