Trouble shooting for the motor of ore milling equipment


In the actual use of the ore milling equipment, we may meet a lot of faults. The motor is the key part of the ore milling equipment. If the motor has some faults, the working efficiency of the ore milling equipment will be affected. Therefore, the troubleshooting for the motor of the ore milling equipment is very important.
If the motor can’t start after the power of the ore milling equipment is turned on, there may be the following reasons.
First, the short circuit, the open short circuit or the grounding phenomenon of the stator winding phase may occur. Second, connection of the stator winding is wrong. Third, the overload is overweight or the rotor is blocked.
You can take these measures. First, check the open circuit, short circuit and the ground connection and repair them. Second, check the ground connection of the stator winding and correct it. Third, lighten the load and eliminate obstacles.
If the shell of the motor of the ore milling equipment is charged, there may be the following reasons.
First, the ground connection is bad. Second, the winding insulation is damaged. Third, the stator winding is affected with damp. Forth, the wiring board is damaged, or there is too much dust.
You can take the following measures. First, find out the causes and repair the motor. Second, repair the insulation, and the impregnating drying process need to be done. Third, replace the wiring board and clean up the dirt.
If the temperature rising of the motor ore milling equipment is too high or the motor smokes, there may be the following reasons. First, the load is too overweight. Second, the short circuit of the stator winding occurs. Third, the ground connection of the stator winding is wrong. Forth, the grounding of the stator winding and the short circuit of the inter turn occur. Fifth, the rotor of the motor of the ore milling equipment breaks. Sixth, the fixed rotors rub with each other.
You can take the following measures. First, reduce the load or replace the vibration motor. Second, repair the short circuit parts. Third, check the ground connection of the stator winding and correct it. Forth, detect the failure and repair it. Fifth, replace the rotor. Sixth, measure the air gap of the vibrating motor. Seventh, check the assembly and attrition of the bearing and repair them.
