The linear motor has a compact structure, low power consumption, fast operating speed, and high acceleration. By directly driving the load, high-precision position positioning control from high speed to low speed can be achieved. Linear motors have a low failure rate, are maintenance free, and have a long service life. If the environment is not handled correctly, many problems may arise. How to effectively control these issues has become one of the considerations for many manufacturers.
The following is a summary of common problems with linear motors: Problems caused by moisture. When water and particulate matter mix in the air, it can cause fatal damage to the motor, further shortening the service life of the linear motor. There are also power supply issues, as harmonic currents caused by high-frequency switching and pulse width modulation can cause voltage and current distortion, overload, and overheating. This shortens the lifespan of the motor and components, and increases equipment costs. In addition, the voltage itself may be too high or too low. To solve this problem, we must continue to pay attention to and inspect the power supply.
Dust and particulate matter, as well as various suspended particles that pollute the air, can enter the motor and cause various hazards. Corrosion particles wear parts and conductive particles interfere with partial current. Once these particles block the cooling channel, they will accelerate overheating.
Overheating is also the main cause of motor failure. In theory, for every 10 ℃ increase in heat, the lifespan of the insulated winding is halved. Therefore, the best way to extend the service life of a motor is to ensure that the motor operates at the appropriate temperature. Improper lubrication is a matter of lubrication level. Excessive or insufficient lubrication can cause injury. In addition, attention should be paid to the issue of contamination in lubricating oil and whether the lubricating oil used is suitable for the current needs.
Common problems with linear motors:
1. Heating problem
2. Load interference issue
3. Magnetic isolation and protection issues
4. The problem of self weight in vertical feed
