  • Causes and countermeasures of noise generated by general vibration motors

    As the vibration source of mechanical equipment, vibrating motor is widely used in vibrating equipment such as vibrating screen, vibrating feeder, silo wall vibrator, vibrating hoist, etc. The vibrating motor generates very little noise during operat...

  • Manufacturing process of plastic commutator

    In the geared motor, the plastic commutator generally has the following main manufacturing processes (take the mica plastic compression commutator as an example): Commutator piece and mica piece manufacture, commutator piece assembly manufacture, pla...

  • Regular maintenance of motor carbon brushes

    Motor carbon brushes are the general term for carbon brushes and generator carbon brushes. The motor carbon brushes look a bit like a pencil eraser. There are wires on the top that lead out, and the size is large or small. The motor carbon brushes sh...

  • What losses are easily caused by traction motor load failure

    Traction motors are affected by various loads during actual operation, including various alternating loads, impact loads caused by subgrade track joints and turnouts, and even various dynamic loads generated randomly. This complex load situation caus...

  • What are the reasons why the oxide film of the commutator brush cannot be formed

    Strengthen the understanding of the oxide film on the surface of the brush, and create the conditions for its formation and normal operation. If the oxide film lubricating layer on the surface of the brush cannot be formed, it means that some conditi...

  • Forms, problems and shortcomings of traditional motor test platforms

    In modern motor testing, it is necessary to verify the performance of the motor for a long time. It is more important to verify the performance under load conditions and sudden changes in the load. Therefore, solving the load problem used in the oper...

  • Preventive measures of traction motor over-voltage

    Due to the different causes of over-voltage, the countermeasures adopted are different. For over-voltage during parking, if there is no special requirement for the stopping time or position, then the method of extending the inverter deceleration time...

  • What components are needed for a simple commutator

    Composed of a set of contact rods fixed on the rotating shaft of the machine, and connected to the armature winding is the commutator; when the shaft rotates, the commutator will reverse the flow of current in the winding, for a single electric Pivot...
