Abstract

The invention discloses a direct-current servo motor with good magnetic field pushing coherence, and relates to the technical field of direct-current servo motor innovation, the direct-current servo motor comprises a direct-current servo motor body, the left side of the direct-current servo motor body is movably connected with a vibration reduction box mechanism, and the vibration reduction box mechanism comprises a second spring; a motor shell mechanism is fixedly installed on the outer surface of the direct-current servo motor body, and a magnetic field attenuation mechanism is movably connected to the outer side of the direct-current servo motor body. The magnetic field attenuation mechanism covers the direct-current servo motor body, the iron plate covers the outer side to shield certain magnetic field interference, the iron-nickel alloy strips and the iron-nickel alloy frame are made of high-magnetic-permeability materials to form a net-shaped shielding structure, the aluminum strips are made of non-magnetic-permeability materials, and the space between the iron plate and the net-shaped structure is filled with the aluminum strips to form a combined shielding structure. The problem that an internal magnetic field and an external magnetic field influence each other is solved, and the effects of working independently, reducing mutual interference and ensuring pushing continuity are achieved.

Description

technical field [0001] The invention relates to the innovative technical field of DC servo motors, in particular to a DC servo motor with good magnetic field driving coherence.

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
