Insulation Resistance Motor

Insulation Resistance Motor

If removing the bearing and greasing of insulation resistance motor, the lubricating grease filled shall account for two thirds of bearing chamber. The scraper used should be avoided from touching any part of the bearing, because these residual fibers may be wedged between rolling elements and lead to damage, especially small bearing.

Technical Parameters

Title:

Insulation Resistance Motor

 

 

Brief Introduction

 

While repairing the motor, it is required to remove the motor as per the following steps. The rotor can be removed from the shaft extension end or fan end. When the rotor is removed from the fan end, the fan is not necessarily removed. While removing the rotor, attention should be paid to protect the winding, to prevent from damaging the stator winding and insulation.

 

When the rotor is not assembled temporarily, it is required to protect the bearings and grease at both ends. The removed parts should be stored centrally, to prevent from losing.

 

To avoid the problem while assembling, it is recommended to complete the position identification before disassembly, and take photos and keep records if necessary.

 

While replacing the winding, it is required to record the type, size, number of turns, wire gauge, and other data of original winding. When the data is inconsistent with the original data, some performance of motor will be changed or cannot be used.

 

While removing the winding, it is recommended to use the electric heating method. The method of burning the stator core is prohibited. This method may make the loss of stator core increase and make the motor efficiency drop sharply. The motor must be repaired by the technician with professional training in the clean and dry place.
