Installation process of DC motor governor
厂家讲到其结果直接影响直流电机调速器的使用。 The DC motor speed regulator should be contacted by everyone. Due to its low noise and power saving characteristics, it has been widely used in industry, and its installation is a concern of everyone. DC motor reducer manufacturers have directly affected the results Use of DC motor governor.
1. Connect the AC power cord and connect the excitation voltage according to the positive and negative values, otherwise it will cause reverse.
2. At the output of the main armature circuit, the + pole is connected to the positive pole of the DC motor main armature, and the-pole is connected to the negative pole of the main armature.
3. The speed feedback + pole is connected to the positive pole of the speed generator feedback signal, and the speed feedback-pole is connected to the negative pole of the speed generator feedback signal.
4. Place the DC governor case in a well-ventilated, non-corrosive gas place. Check if the internal screws are loose due to transportation.
5. Before operation, turn the manual adjustment potentiometer on the panel to the zero position. Then apply the power supply voltage and then turn the manual adjustment potentiometer knob.
厂家提醒大家务必要注意安全问题，再将上述标准过程掌握起来，然后再进行安装，相信大家一定会更好的使用直流电机调速器的。 Before the installation of the DC motor speed regulator, the manufacturer of the DC motor speed reducer reminds everyone to pay attention to safety issues, then master the above standard process, and then install it. I believe that everyone will better use the DC motor speed regulator .
What to do if the DC motor speed drops
Due to the working time process of DC motors, the problem of speed drop sometimes occurs.
1. Broken cage bars.
If the cage rotor breaks, the pointer of the stator ammeter will swing back and forth during the operation of the motor, and sometimes sparks fly out of the explosion-proof motor and emit a buzzing sound. Use the broken strip scout or iron powder method to find Where broken bars fail, take corresponding repair measures.
2. The power supply voltage is low.
Check the voltage at the input terminal of the explosion-proof DC motor and adjust the power supply voltage after confirming that the power supply voltage is too low.
3. The wiring of the stator winding of the explosion-proof motor is incorrect.
If the stator winding is D-connected during normal operation, it is wrongly formed into Y-connected, which should be checked and corrected.
4. The load is too heavy.
It indicates that the starting torque of the DC motor is low, which is not enough to drag the rotating mechanical equipment to reduce the rotation speed. Try to reduce the load.
厂家提示客户，绕线型转子有一相断相、焊点脱焊、电刷接触不良、外部接线短路等，可应用校灯火万用表等工具，检查短路处并排除。 DC motor reducer manufacturers remind customers that the wound rotor has a phase failure, solder joint desoldering, poor brush contact, and external wiring short circuit. Tools such as a school lamp and multimeter can be used to check the short circuit and eliminate it.
