Major flaws in motor bearing design can lead to overheating, causing potential damage to 3 Phase Induction Motor and its components.
(1) The 3 phase electric ac motors’ rotor has major defects that cause it to heat up severely, such as broken bars and severe thin bars, large pores in the end ring, and serious aluminum penetration between the plates. Under the action of heat conduction, the bearing grease melts and runs away or even dries up, and the friction resistance rises sharply, generating high heat.
(2) The diameter of the bearing chamber is too large, causing the outer ring of the bearing to slide and rub in it for a long time, generating high heat. In addition, in this state, the heat conduction between the bearing and the bearing chamber will also be affected, causing its temperature to rise.
(3) Due to structural design defects, the bearing part cannot dissipate heat well.
To summarize, major flaws in motor bearing design, such as bearing chamber diameters that are too large, can lead to overheating. Addressing these design flaws and ensuring proper maintenance practices are critical to preventing overheating and maintaining optimal performance of motor bearings.
