微型电机厂家分享导致直流电机转速下降的原因 

来源:http://www. 发布时间:2020天天彩票网站-05-27 浏览:
  1.笼形转子断条:若笼形转子断条现象发生,直流电机定子电流表指针在运行时会来回摆动,有时防爆电机会飞出火花并发出嗡嗡声 。采用断棒探伤法或铁粉法找出断棒故障,并采取相应的修复措施 。
  1. Broken cage rotor bar: if the broken cage rotor bar occurs, the pointer of DC motor stator ammeter will swing back and forth during operation, and sometimes the explosion-proof motor will fly out sparks and make a buzz. The method of broken bar flaw detection or iron powder is used to find out the broken bar fault, and corresponding repair measures are taken.

  2.电源电压偏低:检查防爆直流电机输入电压,确认电源电压过低后调整电源电压 。
  2. low supply voltage: check the input voltage of the explosion-proof DC motor, and confirm the power supply voltage after too low power supply voltage.
  3.防爆电机定子绕组接线错误:d型定子绕组在正常工作时接线,经检查后应予以纠正 。
  3. Wrong wiring of explosion-proof motor stator winding: Type D stator winding is wired in normal operation, and shall be corrected after inspection.
  4.重负荷:说明直流电动机的起动 力矩较低,不足以拖动旋转机械设备,使转速下降,应降低负荷 。
  4. Heavy load: it indicates that the starting torque of DC motor is low, which is not enough to drive rotating mechanical equipment, so as to reduce the speed, so the load shall be reduced.
