What Are The Factors That Affect The Life Of Micro Motors?

There are many reasons that affect the life of the micro motor, the following is to introduce a few common factors
1. the impact of load current fluctuations
If the motor circuit is turned on and off frequently, the load current will fluctuate frequently, resulting in sharp changes in the current within a short period of time, generating significant additional forces in the motor windings and current-carrying conductors that are related to the square of the current and act on the fixed parts through the insulation of the current-carrying conductors. The windings will suffer damage and reduce the service life of the motor.

2. Effects of steering changes and fluctuations and reversal processes
As a result of these processes, the insulated wires used in the moving parts will experience an increase in mechanical forces, and mechanical joints like laminated sets and declarer shafts will also experience an increase in load. As a result, these mechanical joints and moving parts will become worn and lose their functionality.
3. Effects of thermal overload
Thermal overload can damage the insulation material because the insulation material has a maximum allowable temperature. When the operating temperature of the motor exceeds the allowable limit temperature of the insulation material, the insulation material will be damaged, resulting in a shortened service life of the motor.

4. The effect of temperature change
Temperature fluctuation is the temperature change between the cold and hot state of the motor. It will lead to different degrees of expansion of wires, insulation and cladding parts, which will shorten the service life of the motor and easily lead to paint stripping and loosening. Temperature fluctuations can be particularly pronounced if the motor is subjected to alternating loads.
