The small 12v dc motor factory tells you about the integrated settings of the DC decelerating motor.
The use of DC decelerating Motors is supported by integrated circuits, so their selection and design are particularly important. Here are two points to note.
1, collector ring structure collector ring structure according to its nature of use is divided into: overall plastic die-cast collector ring(for small motors); Equipped collector ring(medium motor); Screw assembly type collector ring(medium and low speed large motor); Heat sleeve collector ring(for high speed Motors).
2, the selection of the collector ring material according to the electrical conductivity, sliding contact with the brush, must have wear resistance and stable sliding contact characteristics, as well as mechanical strength requirements, sliding ring can be made of brass, bronze, low carbon steel or medium carbon steel., The sliding ring of the high-speed motor is made of high-strength alloy steel(such as 35Smine). For corrosive sites, stainless steel sliding rings can be used, but the sliding characteristics of stainless steel are unstable, and the improper combination with the brush often causes the brush to beat, which can easily cause the brush temperature to rise too high or abnormal wear. This material is not used as much as possible.
In mines, metallurgy, cement plants and other industries, DC decelerating Motors 'collector rings and brushes are used to turn on the starting resistor, and the rotor windings are short-circuited after the motor is started. In order to reduce the wear and heat of DC reducer's collecting ring and brush during the whole life, the selection of collecting ring and brush is very important to the winding rotor motor.
