400V/50HZ Hollow Shaft Motor Hydraulic Pressure 112M1-4 7.5HP 5.5KW 4 Pole

 

Hollow Shaft Electric Motor Description

 

112M1-4 hollow shaft electric motor uses a hollow metal tube design to reduce the overall size of the hollow shaft. The fully enclosed self-fan-cooled squirrel cage structure, aluminum housing,100% copper wire, C & U bearings, using high-quality materials, low-temperature rise, fast heat dissipation, Long service life, energy-saving, ample starting torque, low noise, slight vibration, and so on. , The assembly process is rigorous. The shaft lift is subjected to high-frequency hardening, which significantly improves mechanical strength, IEC standards and seamlessly connects with professional equipment to achieve worry-free operation. It is one of the ideal choices for the power of cleaning equipment.

Industry Information:

Summarization and analysis of the causes of heating of motor bearings

 

A heating problem caused by an improper lubrication system. We have discussed this problem in many previous articles. One case is the unsuitability of the design itself. For example, the bearing oil cavity is too large and cannot form a good circulation, which will cause the bearing to occur; excessive grease filling will cause the bearing system to dissipate heat Poor; the grease does not match the working conditions, resulting in thermal degradation or cold accumulation of the grease, which will cause the bearing to heat up due to poor lubrication; especially during the operation of the motor, regular maintenance and maintenance are particularly important.
