Commutator manufacturers and distributors with high production standards are looking for high-quality customized silicon steel sheets for electrical excitation high melt applications, along with other special properties such as full lamination, excellent resistance to temperature and dust.

The occurrence of cracks or penetration in the insulation between the commutator blades is due to the vibration and impact on the overall electrical strength of the commutator surface. The smoothness of the commutator surface directly affects the internal structure of the motor. In this case, a very small scar will appear on the surface of the commutator, such as wrapping the shaft light with gold paper first, in order to solve the untreated problem.

The commutator itself is charged, and there is an outer insulation layer on its surface that can be directly breakdown. But if the wire core of the motor is damaged, it will have an impact on the internal safety of the motor. The enclosure of explosion-proof motor is called interphase winding. The iron core is first made of Hot-melt adhesive, without directly solidifying the iron core inside the insulation of the rotor iron core, and then it can be removed.

The surface of the commutator is covered with a thin layer of oil stain, making the surface layer more heavy. Then, a hair dryer is used to mix it into powder, continuously sticking the oil stain onto the rotor coil,

Maintaining the cleanliness of the entire machine depends on the working conditions of the commutator. We don't talk much here because the working conditions of the commutator are more than humidity, vibration, etc. If the brush is worn too much, it is easy to cause the motor to be unable to operate normally. The working state of the motor should be adjusted according to its working principle to meet the working requirements for normal operation.

Flutter caused by uneven or uneven brush pressure. When the stepper motor runs at low speed, the vibration and noise of the motor will greatly increase, and attention may even be paid to damaging the motor.

When the mica sheet or mica sheet on the uneven surface of the commutator is larger or lower than 006mm, and there is a pulsation of the brush or mica sheet, it can be adjusted to the uneven position.

The main reason for uneven runout of the commutator is the inconsistent size of the mechanical structure and electrical clearance. Due to different mechanical processing, vibration and imbalance can occur when the commutator rotates.

Decompose the pulse frequency, with a large frequency fluctuation and a continuous range value of 1000 Hz. Under no load, the frequency fluctuation is 258% Hz. Due to fluctuations in the voltage drop and embedding frequency of the outgoing line, the contact resistance between the brush and the commutator will increase, leading to vibration of the vibration source. The vibration also causes loosening of the piston rod or clamp, resulting in a decrease in the contact resistance between the brush and the commutator.

Springs under different brushes contain varying degrees of difference, and critical springs with different diameters. The larger the distance between the brushes, the smaller the gap between the springs when subjected to vibration force, and the more the spring increases.

The surface oxide film of the commutator is too thick, and the contact voltage drops can cause wear on the brush and commutator. Therefore, HT300 commutator should be chosen.

After the mica between the commutator plates shrinks, it bounces with the impact of the commutator lifting plate.
