 There are two kinds of fixed speed type polishing motors and variable speed polishing motor. To choose from, to meet the needs of manufacturers of a variety of polishing. 



 Polishing the installation of the motor: 


 1, the motor's installation location. Should ensure good ventilation and cooling conditions; 

 2, the motor should be installed in sufficient rigidity of the steel plate or reinforced concrete structure. To prevent the larger vibration affect the life of the motor running; 

 Cloth wheel shaft installed, should be effectively good balance, to prevent the increase of the motor vibration affect the life of. 

 The operation of the motor: 

 1, the motor should be properly grounded grounding device, the junction box; 

 2, the motor wiring board 6 terminal, beginning end: U1, V1 and W1. The end of: U2, V2, and W2. 

 3, according to the access method specified on the nameplate, then into △ connection or Y connection: 

 4, the motor should have thermal protection, short circuit protection, electric leakage protection device. And pay attention to adjust the setting value of the protection device; 

 5, the motor is generally for the biaxial stretch (tapered threads or straight shaft with thread) rotating threaded shaft extension opposite. Should pay attention to the use of one end of the shaft turn the momentum direction of its arrow mark to ensure that the shaft rotation direction and rotation of the shaft threads to the contrary, in order to prevent the occurrence of loose cloth wheel, otherwise should be corrected before use; 

 Fourth, the maintenance of the motor: 

 1, the motor grease at least one year replacement time, the amount of grease to fill the bearing cavity 1/3 to 1/2 as well (closed bearings do not have to replace the grease lifetime), high-power polishing motor end caps with oil cup, note that the right amount of fuel oil caused by excessive bearing overheating; 

 2, the motor is used, if different sound, burning smell, smoke or speed decreased, should immediately stop, analyze the reasons for maintenance, troubleshooting before use. 

 3, the bearing temperature shall not exceed 95 ℃, or the bearing oil dry metamorphism, should pay attention to stop the check and replace the bearings, to prevent burn out the bearings resulted in the burning motor.
