Clockwise Rotation 24mm 220-380V IE2 Hollow Shaft Motor

Hollow Shaft Motor

Hollow Shaft Electric Motor Description

Three-phase aluminum housing hollow shaft motor for pressure washers, entire copper coil, fully enclosed design, air-cooled, hollow metal tube design, squirrel cage A.C. asynchronous motor. The motor has good thermal conductivity, low current, low-temperature rise, good heat dissipation, low noise, ample starting torque, compact structure, and simple operation.

It is a 100% copper coil, high-quality bearing, high and light rotor, and rigid assembly. The shaft lift is subjected to high-frequency quenching treatment, which significantly 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.

Industry Information

Summarization and analysis of the causes of Heating of motor bearings

They are bearing ablation caused by electric corrosion. This problem is the current shaft problem we initially talked about. The necessary conditions for shaft current 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 severe 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 used for self-service car washes and professional high-pressure washers that require a longer service life.
