，
MC series aluminum housing capacitor start 3hp 220v single phase motor is made of selected quality materials and conform to the IEC standard. MC has good performance, safety and reliable operation, nice appearance, and can be maintained very conveniently, while with low noises ,little vibration and at the same time of light weight and simple construction. High starting torque, perfect starting performance, generally the multiple of the starting torque can be up to 3.0 times. The motor is used in the occasions where big starting torque and small starting current such as air-compressors, pumps, refrigerators, medical apparatus and others with full-load start.

Common failures of vertical motors
1. Thrust pad burnout Thrust pad is a key component of a large vertical motor. According to statistics, the thrust pad burning failure accounts for about 40% of the equipment failures of the water pump unit. The fundamental reason is that the oil film layer between the thrust pad and the mirror plate is destroyed, the frictional heat increases rapidly, and the temperature of the tile surface exceeds the melting point of the tile surface babbitt alloy, resulting in burning. The current solutions mainly include: increasing the area of the existing babbitt alloy thrust pad, increasing the overload capacity of the thrust pad, adopting a hydraulic jacking device (opening a hole in the center of the thrust pad, injecting high pressure oil to promote oil film formation), ensuring the thrust head and The machining accuracy of the contact surface between the thrust pads, and the improvement of the cooling capacity of the water cooler in the fuel tank, etc.
