DC motors are ubiquitous power devices in modern society, but they are not machines that run forever. Let's learn about why DC motors fail and what measures we can take to extend their lifespan.
1. The influence of human factors:
Operational errors are a significant factor in DC motor failure. Rough handling, such as accidentally dropping it or improper use, can damage internal components, rendering the motor malfunction. Furthermore, electrostatic discharge (ESD) is also a serious issue, especially for brushless motors. ESD can damage internal sensors, thereby affecting the motor's control and feedback systems.
2. Environmental factors considerations:
Environmental conditions also have a significant impact on DC motors. For example, temperature and humidity directly affect the motor's operating condition. At extreme temperatures, lubricant may freeze or turn into liquid, affecting bearing lubrication and increasing friction and wear. In high humidity environments, bearings may corrode, leading to malfunctions or even motor failure.
3. Selection of motor wiring plug:
For high-current motors, choosing the right connector is crucial. The material and performance of the connector may change under different temperature and humidity conditions; improper selection can lead to connector failure, thus affecting the normal operation of the motor.
