Three-phase motor price Three-phase motor common faults

The price of three-phase motors varies depending on factors such as brand, model, power, and material. Here are some common three-phase motor price ranges:

The price of a small power (0.18kW - 1.5kW) three-phase asynchronous motor ranges from a few hundred yuan to a thousand yuan.

The price of medium-power (2.2kW - 15kW) three-phase asynchronous motors ranges from one thousand yuan to several thousand yuan.

The price of high-power (20kW - 100kW) three-phase asynchronous motors ranges from several thousand yuan to tens of thousands of yuan.

It should be noted that the price of three-phase motors is also related to market conditions, supply and demand, and other factors, and the price will fluctuate. In addition, you should also consider the purpose, performance and quality of the three-phase motor and choose a three-phase motor that suits your needs.

Common faults, causes and solutions for three-phase motors are as follows:

1. Causes of insulation failure: Long-term use, high temperature environment, overvoltage and other conditions may cause insulation aging, which in turn leads to insulation failure. Solutions: Replace insulation materials, clean the dirt inside the motor, strengthen maintenance, etc.

2. Bearing failure causes: Long-term use, overload, poor lubrication, etc. may cause bearing damage. Solution: Replace the bearing, add appropriate amount of lubricating oil, adjust the bearing clearance, etc.

3. Causes of power failure: Power supply voltage fluctuation, power failure, line failure, etc. may cause power failure. Solution: Adjust the power supply voltage, replace damaged power supply components, ensure power supply stability, etc.

4. Causes of overload: Long-term overload, instantaneous excessive load, etc. may cause motor overload. Solution: Reduce the load, adjust the motor operating parameters, change the motor grade, strengthen maintenance, etc.

5. Causes of coil failure: Long-term use, overvoltage, etc. may cause the coil to age and become damaged. Solutions: Replace the damaged coil, repair the coil, clean the coil, strengthen maintenance, etc.

6. Causes of mechanical failure: Long-term use, overload, wear of mechanical parts, etc. may lead to mechanical failure. Solution: Replace damaged mechanical parts, adjust the position of mechanical parts, strengthen maintenance, etc.

7. Causes of humidity failure: Long-term use, humid environment, etc. may cause humidity failure. Solution: Strengthen maintenance, clean the inside of the motor, improve the sealing of the motor, etc.

It should be noted that the maintenance measures taken for different faults are different. If you are not sure how to perform the maintenance, it is recommended to ask professional maintenance personnel to handle it. At the same time, in daily use, strengthening maintenance and regularly checking the operating status of the motor are also very helpful in preventing and solving faults.
