What factors affect the lifespan of micro-gear motors?

The following factors affect the lifespan of gear motors:
1. The impact of load current fluctuations. If the motor circuit is frequently connected and switched, the load current will also fluctuate frequently, causing short-term and rapid changes in current. This generates significant additional forces in the current-carrying conductors and motor windings. These forces are related to the square of the current and act on the fixed components through the insulation of the current-carrying conductors. Over time, this damages the insulation, causing faults such as short circuits or open circuits, damaging the windings and shortening the motor's service life.
2. The impact of rotational fluctuations and reversals. These processes generate additional mechanical forces in the insulated conductors that act on the moving parts. Mechanical connectors such as the lamination stack and shaft also exert additional loads, causing fatigue and loss of function.
3. The impact of thermal overload and temperature fluctuations. Thermal overload can damage the insulation material. Because the maximum temperature is directly related to the service life of the insulation material, the motor's operating temperature must not exceed the insulation material's maximum temperature limit. Temperature fluctuations also affect the insulation material's service life. Temperature fluctuation refers to the temperature difference between the motor's cold and hot states. This effect is particularly pronounced when the motor is subjected to alternating loads. Temperature fluctuations typically cause varying degrees of expansion and contraction in conductors, insulation, and packaging, which can easily lead to paint peeling and loosening, shortening the lifespan of the Jingcheng motor.

4. The impact of the reducer's operating environment. Motors used in mining and the chemical industry, for example, operate in harsh environments and are susceptible to environmental influences that can shorten their service life. For example, impure media, corrosive gases, and high temperatures can impair the motor's electrical and mechanical performance. Therefore, when selecting a motor, it is crucial to choose one with appropriate protective structures based on environmental conditions. Gear reducers are suitable for operating temperatures ranging from -10°C to +40°C and humidity below 90%.
