Adaptation features
Power matching: Depending on the exhaust volume and working pressure of the air compressor, the motor power ranges from several thousand watts to several hundred kilowatts, ensuring that the output power meets the requirements for compressed air production.
Starting performance: The air compressor is a load-starting device. Some motors are equipped with voltage reduction starting devices (such as star-delta starting, autotransformer starting) to reduce the impact of starting current on the power grid.
Protection level: Considering that the working environment of the air compressor may have dust, oil, etc., the motor usually adopts protection levels such as IP54, IP55, etc., to prevent foreign objects from invading and affecting operation.
Insulation level: Most use F-class or H-class insulation, which can withstand higher temperatures and adapt to the heat environment generated by the long-term continuous operation of the air compressor.
Common faults and maintenance
Overheating: May be caused by abnormal voltage, excessive load, poor ventilation, or bearing wear. Regularly clean the motor surface dust, check the cooling fan and ventilation channels.
Strange noise: Usually related to bearing wear, rotor scuffing, or stator winding faults. Discovering abnormalities, stop the machine in time for inspection and replacement of damaged components.
Abnormal vibration: May be caused by unstable installation, unbalanced rotor, or eccentric coupling. Re-calibrate the installation accuracy.
Winding faults: Such as short circuit, open circuit, or grounding, need to detect through insulation tests (megohmmeter), and if necessary, re-wire the winding. Importance
The stable operation of three-phase induction motors is directly related to the gas production efficiency and safety of the air compressor. Selecting the appropriate specification of the motor and conducting regular maintenance (such as checking the terminal connections, lubricating the bearings, measuring the insulation resistance, etc.) can effectively extend the overall service life of the air compressor and reduce the failure rate.
