What are the factors that affect the life of micro-reduction motors?

1. The influence of load current fluctuations. If the motor circuit is frequently connected and switched, the load current will also fluctuate frequently, causing the current to change sharply in a short time, thereby generating obvious additional forces in the current-carrying wires and motor windings. These forces are related to the square of the current and act on the fixed parts through the insulating material of the current-carrying conductor. Over time, the insulation is destroyed and short circuits or open circuits are caused, causing the windings to be damaged and shortening the service life of the motor.

2. The influence of the change and fluctuation of the rotation and the reversal process. These processes will generate additional mechanical forces in the insulated wires to act on the moving parts. At the same time, mechanical connectors such as laminations and shafts will also generate additional loads, so that these moving parts and mechanical connectors will fatigue and lose their working ability.

3. The influence of thermal overload and temperature fluctuations. Thermal overload will damage the insulation material. Because the maximum temperature is directly related to the service life of the insulation material, the operating temperature of the motor is not allowed to exceed the allowable limit temperature of the insulation material. Temperature fluctuations also affect the service life of the insulation material. The so-called temperature fluctuation refers to the temperature difference between the cold state and the hot state of the motor. The above effects are particularly evident when the motor is subjected to alternating loads. Usually, temperature fluctuations will cause different degrees of expansion changes in the wires, insulation layers and wrappings, which can easily cause paint peeling and loosening, and shorten the service life of the Jingcheng motor.
4. The influence of the environmental conditions of the reducer, such as locomotive motors. Mining motors and chemical industry motors work in different harsh environmental conditions and are easily affected by the environment and shorten their service life. For example, impure or corrosive gases in the surrounding medium and high temperatures will damage the electrical and mechanical properties of the motor. Therefore, when selecting a motor, you must select a motor with a corresponding protective structure according to the environmental conditions. The gear reducer is suitable for an ambient temperature of minus 10 degrees to plus 40 degrees and a humidity of less than 90%.
