Three Phase Hollow Shaft AC Motor 7.5hp 1450Rpm 5.5kw For Cleaning Machine

Three-phase hollow shaft A.C. motor 7.5hp 1450Rpm for cleaning machine

Hollow Shaft Motor

Hollow shaft motor uses 100% copper coil, high-quality bearing, high precision rotor, fully enclosed phoenix squirrel cage, hollow metal tube, new motor with internal joint, which reduces the overall size of the hollow shaft and maintains the standard motor All technical and maintenance advantages. The hollow shaft design dramatically reduces the quality of parts and better achieves the goal of weight reduction. The open shaft motor has the characteristics of a small current, low-temperature rise, good heat dissipation, and low noise. Seamlessly connect with professional equipment for worry-free operation. Ideal for cleaning equipment power systems
