Problems solved by technology

[0002] The existing wire feeding motors and wire feeding devices for welding wire feeding mainly have the following disadvantages: (1) The motor adopts a long cylindrical brushed permanent magnet DC motor, which not only slows the dynamic response speed, but also shortens the life of the wire feeding motor products. Seriously affected by the short life of the long cylindrical brushed permanent magnet DC motor; (2) The output end bearing structure of the deceleration transmission device is unreasonable, and it is very easy to cause the inner ring or outer ring of the output end bearing to match the matching parts in practical applications. Relative sliding occurs on the surface of the bearing, which leads to the premature failure of the rolling bearing function of the output bearing and affects the working accuracy and product life; (3) The axial positioning accuracy of the reduction transmission device is poor, the noise is large, and the response speed is also slow
Because the outer side is often the side that is easy to be touched, the brush assembly or the magnetic steel is often damaged due to various touches, causing the motor to fail to work normally; at the same time, due to the existence of the brush assembly on the outer side, it also causes Difficult to mount a tachometer on this side
