Hollow Shaft Electric Motor Description
The hollow shaft motor is a new motor with an internal joint designed for high-pressure pumps. It reduces the overall size of the hollow shaft and maintains all the technical and maintenance advantages of a standard motor. It adopts a new technology design, 100% copper wiring, C&U bearing, and shaft extension through high-frequency quenching treatment, significantly improving mechanical strength, low-temperature rise, fast heat dissipation, high efficiency, and energy-saving. In addition, it is connected to the pump for high-pressure water column cleaning.
Mode: 112M2-4 Horsepower: 7.5
RPM:1400 Shaft Size:24mm Hollow
Voltage: 400V Hertz: 50
Motor housing: Aluminum Bearing: C&U
Shaft: C#45 Insulation: Class F
Protection: IP55 Installation: B3 Hollow shaft
Stator&Rotor: 1. Cold-rolled silicon steel sheet by high-speed punching machine. 2. 100% high-quality copper wire
Advantage:
1. Use high-quality materials to ensure sufficient output power, small working current, effectively reduces temperature rise, good heat dissipation, and high efficiency.
2. the use of high-quality bearings and rigorous assembly process to achieve low noise operation.
3. tailor-made for professional equipment, shaft extension through high-frequency quenching treatment significantly improves mechanical strength, seamless connection with equipment, and worry-free operation.
