Hollow Shaft Electric Motor Description
Three-phase aluminum housing hollow shaft motor for pressure washers, full copper coil, fully enclosed design, air-cooled, hollow metal tube design, squirrel cage AC asynchronous motor. The motor has good thermal conductivity, low current, low-temperature rise, good heat dissipation, low noise, large starting torque, compact structure, and simple operation.
It is 100% copper coil, high-quality bearing, high and light rotor, and rigorous assembly. The shaft lift is subjected to high-frequency quenching treatment, which greatly improves the mechanical strength, maintains all the technical and maintenance advantages of the standard motor, and conforms to the IEC standard. Therefore, it is an ideal choice for cleaning equipment.

Summarization and analysis of the causes of heating of motor bearings
Bearing ablation caused by electric corrosion. This problem is the shaft current problem we originally talked about. The necessary conditions for shaft current to occur are shaft voltage and closed loop. Will generate shaft voltages of varying degrees for motors used under variable frequency conditions and high-power and high-voltage motors. When the shaft voltage that the lubricant’s insulation cannot withstand occurs, the larger shaft current will form a closed loop through the bearing and cause ablation problems to the components of the bearing system. The initial stage of ablation is bearing noise and accompanied by Heating. In a short time, it will cause the serious failure of the bearing system due to damage to the bearing components and heating problems.
Hollow Shaft Electric Motor Application
Hollow shaft motor connection high-pressure pump use for self-service car washes and professional high-pressure washers that require a longer service life.
