Motor low-voltage operation will also lead to heating problems, when the asynchronous motor is in a state of low-voltage operation for a long time, the current will be greatly increased, and the lead wire will need to withstand a larger current, especially some lead wire diameter choice is not very large, the larger current density will directly lead toThree-phase asynchronous motorThe lead wire is hot.
For example, the lead wire of the winding rotor produces heating phenomenon, which is a special fault, which may be related to the welding of the wire, and the quality of welding will directly affect the lead wire, resulting in this phenomenon;
But there are many other reasons for this phenomenon, it is a more complex problem, for this type of asynchronous motor, the ventilation and heat dissipation of the collector ring is very critical, for the three-phase motor collector ring, the temperature of the three torus has a significant difference, so it will also affect the rotor lead temperature, but different motor influence is different.
