Problems solved by technology

[0003] 1. The DC servo motors of the prior art are installed in a relatively fixed position to work during daily use. When working in a magnetic field, the internal magnetic field and the external magnetic field will affect each other, resulting in weakening of the strength of the internal and external magnetic fields or Strengthening will affect the stability of the DC servo motor rotation and the continuity of the drive;
[0004] 2. The DC servo motor in the prior art uses a metal plate shell, which has a high-strength protection effect, but at the same time it will also cause the weight of the DC servo motor to increase, which will affect the movement of the DC servo motor and increase the servo power to a certain extent. The burden of the motor, while the servo motor is susceptible to the vibration of the fixed carrier
