Brief Introduction

During motor operation, if the shaft of motor with protection class IP55 heating, it is due to the following reasons. From the theoretical analysis, can let a person detect the temperature of the rotor shaft are in the case outside, basically can be circled in the position of the shaft extension, the theoretical analysis, the position because in the motor shell outside, theoretically should be lower than the temperature of the motor shell, if there is a heat problem here, may be in the motor shell, the motor bearing system and the winding temperature will be higher.

From the motor operation mechanism analysis, the motor shaft itself does not produce heat, the shaft heat may be due to other parts of the heat conduction. From the motor operation of the heat factor analysis, if the stator windings or rotor core heat, will be directly or indirectly conducted to the rotor shaft, resulting in a higher shaft temperature; in addition to the motor cavity of the heat conduction factors, if the bearing system temperature is high, it will be more close to the shaft stretching, the rotor shaft here the temperature will be higher.

In addition to the factors of the motor body, the towed equipment heat will also lead to motor shaft temperature; there is another factor, if the motor shaft extension and coupling with bad, there is relative motion, will also lead to motor shaft heat problems occur to varying degrees.

Therefore, when the motor shaft heat, should be necessary to analyze and take measures to solve, in order to prevent serious failures.
