Optimize the motor structure design: Under the condition of frequent start-stop, the structural design of linear motors is crucial. By optimizing the winding layout, reducing the resistance and reducing the heat generated by current changes, the stability of the motor can be effectively improved. For example, copper with high conductivity is used, and the number of winding turns is reasonably planned to reduce the heating of the winding and reduce the insulation aging caused by thermal stress, thereby extending the service life of the motor.
Select high-quality materials: High-quality materials are the basis for ensuring the life of linear motors. The use of high-performance insulating materials can withstand the current shock and temperature changes caused by frequent start-stop. At the same time, the mechanical parts of the motor, such as guide rails and sliders, use wear-resistant and high-strength materials to reduce wear and mechanical fatigue. For example, ceramic-coated guide rails can effectively reduce the friction coefficient, improve wear resistance, and ensure the stability of the mechanical structure of the motor during frequent start-stop.
Improve the heat dissipation system: Frequent start-stop will cause linear motors to generate a lot of heat, and an efficient heat dissipation system is essential. Installing a cooling fan or using a liquid cooling device can dissipate the heat in time. For example, designing heat dissipation fins on the motor housing to increase the heat dissipation area and using fans for forced air cooling can effectively reduce the motor temperature and avoid performance degradation and shortened life due to overheating.
Optimize the control system: Advanced control systems can accurately control the start and stop process of the motor. By adopting soft start technology, excessive current shock when the motor starts can be avoided. At the same time, during the stop process, energy feedback braking is used to convert the kinetic energy of the motor into electrical energy to feed back to the power grid, reducing the wear caused by mechanical braking. For example, using an intelligent frequency conversion controller to adjust the control parameters in real time according to the operating status of the motor to achieve smooth start and stop.
Strengthen lubrication and maintenance: Regular lubrication and maintenance of linear motors can significantly extend their life. Add appropriate lubricants to moving parts such as guide rails and sliders to reduce friction. At the same time, regularly check the operating status of the motor, such as the insulation resistance of the windings, the wear of mechanical parts, etc. Discover and deal with potential problems in a timely manner to prevent small faults from turning into big problems.
Reasonable planning of operating parameters: Reasonable planning of the operating parameters of linear motors according to actual working conditions. Avoid frequent starting and stopping of motors under full load or overload for a long time. For example, according to the load requirements, the motor's operating speed and acceleration are adjusted to ensure that the motor operates in the best working state and reduce unnecessary losses.
Redundant design: For some application scenarios with extremely high reliability requirements, redundant design can be used. Equipped with spare motors or key components, when the main motor fails, the spare motor can be put into operation in time to ensure the normal operation of the system. At the same time, the redundant design can also share the motor's workload, reduce the number of starts and stops of a single motor, and thus extend the overall service life of the motor.
