How to determine the motor rating? What factors need to be considered?

Friend Xiao G asked Ms. Reference: Why did some motors change the power of a brand? Could it be that the price of a new brand of motor has changed? "Oh, this is two things, can't be mixed together." Ms. replied, and explained: First, it is impossible to change the price of a brand of motor; second, some motors are The power of changing the brand has changed because the working system has changed.

The question raised by the small G actually involves the motor rating problem, which is closely related to the applicable load condition of the motor. The rating of electromagnetic devices, such as motors and transformers, is usually determined by both mechanical and thermal considerations, and its lifetime is determined by the maximum temperature that can withstand without being excessively shortened.

Motor life is closely related to its operating temperature

The aging of the insulating material is affected by both the time and temperature factors, so the aging of the insulating material is a chemical phenomenon involving slow oxidation and sudden solidification, and causes damage to mechanical durability and dielectric strength.

Insulation life test

Generally, the working conditions should be simulated as much as possible. These conditions usually include: (1) thermal shock caused by heating to the test temperature. (2) Continuous heating at this temperature. (3) Thermal shock caused by cooling to room temperature or lower. (4) Vibration and mechanical stresses that may be encountered in actual work. (5) Exposure to moisture. (6) Dielectric test to determine the insulation state.
