First, take appropriate repair measures for defective parts. The power supply voltage is low. Please confirm the input voltage of the DC motor, and adjust the supply voltage after confirming that the supply voltage is too low. Excessive load means that the starting torque of the Z4 DC motor is low, pulling the rotating mechanical device to reduce the speed and reducing the load shortage.
Analysis of the countermeasures when the speed of the DC motor decreases.
When a DC motor is running, the speed may decrease due to various reasons. As soon as the speed drops, this will affect the working efficiency of the engine. Therefore, in order to perform appropriate operations, you need to find the right solution at the right time.
1. The cage rotor is broken.
After the cage rotor is damaged, the pointer of the stator ammeter swayed back and forth during the operation of the motor, and sparks flew from the DC motor, making a buzzing sound. Take appropriate repair measures for defective parts.
2. The power supply voltage is low.
Please confirm the input voltage of the DC motor, and adjust the supply voltage after confirming that the supply voltage is too low.
3. Wiring of the stator winding of the explosion-proof motor is wrong.
In normal operation, when the stator winding is connected to D, it needs to be modified after confirmation due to the wrong connection with Y.
4. The load is too high.
It shows that the starting torque of the DC motor is low, and the rotating mechanical device is pulled to reduce the speed and reduce the load shortage.
The above-mentioned situation and solution can deal with the phenomenon of Z4 DC motor speed reduction.
