   Installation process of DC motor governor

We should have been exposed to DC motor speed governor. Because of its low noise and power saving characteristics, it is widely used in industry, and its installation is a concern, DC motor reducer The manufacturer said that the results directly affect the use of DC motor governor.

1. Connect the AC power line and connect the excitation voltage according to the positive and negative, otherwise it will cause reversal.

2. At the output end of main armature circuit, + pole is connected with positive pole of main armature of DC motor and - pole is connected with negative pole of main armature.

3. Speed measurement feedback + pole connected to positive pole of tachogenerator feedback signal, and speed measurement feedback pole connected to negative pole of feedback signal of tachogenerator.

4. Place the DC governor case in a place with good ventilation and no corrosive gas. Check if the internal screws are loose due to transportation.

5. Turn the manual potentiometer on the panel to zero before operation. Then supply the power supply voltage, and then turn the manual adjustment potentiometer knob.

Before the installation of DC motor governor, DC motor reducer The manufacturer will pay attention to the above-mentioned DC speed regulator, and then we will pay attention to the installation process of DC motor.

   How to reduce the speed of DC motor

Because of the working time and process problems of DC motor, sometimes the speed of DC motor will drop. How to deal with this problem

1. The cage rotor bar is broken.

In case of broken bar of cage rotor, the pointer of stator ammeter will swing back and forth during the operation of the motor, and sometimes sparks will fly out of the explosion-proof motor and emit buzzing sound. The broken bar detector or iron powder method shall be used to find out the broken bar fault and corresponding repair measures shall be taken.

2. The power supply voltage is low.

Check the input voltage of explosion-proof DC motor and adjust the power supply voltage after confirming that the power supply voltage is too low.

3. The wiring of explosion-proof motor stator winding is wrong.

If the stator winding with D-shaped connection is wrongly formed into Y-shaped connection during normal operation, it shall be checked and corrected.

4. The load is too heavy.

It shows that the starting torque of DC motor is low enough to drive the rotating mechanical equipment and reduce the rotating speed. It is necessary to reduce the load.

   DC motor reducer manufactor It is suggested to the customer that the winding rotor has one phase open phase, solder joint desoldering, poor contact of electric brush, short circuit of external wiring, etc. the short circuit can be checked and eliminated by using tools such as light calibration multimeter.
