How to solve the problem of winding heating in energy-saving motors?

A netizen mentioned that the winding of his single-phase motor overheated and was burned out. He plans to the number of turns in the main winding and asks whether the number of turns in the auxiliary winding needs to be adjusted. The overheating of the winding in an-saving motor is a specific manifestation of the motor's pathology. There are many reasons that can lead to winding overheating, and to solve this problem, it is to identify the root cause of the overheating. During the design phase of the product, the specific electromagnetic scheme is determined through the calculation and balancing of various factors as current density, magnetic density, and power density. If overheating occurs during the testing and application of the energy-saving motor, specific analysis should be conducted based the specific manufacturing process and application conditions. Energy-saving Motor Theoretically, the temperature rise level of energy-saving motors that are released to the market is qualified When the temperature is too high, the first step should be to check the compliance of the usage, such as whether the rated voltage of the energy-saving motor is far off, whether the energy-saving motor is in an overloaded state, whether the single-phase motor is in an unloaded state for a long time, whether the capacitor is reasonable; whether the ventilation and cooling device of the variable frequency motor is not turned on at the same time, etc. All these unfavorable factors can lead to overheating and even burning out of the energy-saving motor winding. During the production and manufacturing stage of the energy-saving motor, some key factors can also lead to overheating of the energy-saving motor winding, such as the critical insulation treatment process. If the energy-saving motor winding does not go through a strict and effective insulation process, there will be many air gaps inside the winding, and the winding cannot become a relatively solid whole. Improper selection of the fan for the energy-saving, or poor ventilation in the motor, can also lead to adverse consequences that violate the design. However, such problems can only be identified through strict type testing, regular factory testing may mistakenly consider non-compliant products as qualified. All these reasons can lead to high winding temperature rise. The measures to improve the temperature rise level be targeted. Otherwise, the problem cannot be solved.
