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.
