Application

hollow shaft motor is widely used in below:

In the industrial and chemical industries, it is used as mechanical processing, bridge engineering equipment, and unique parts cleaning equipment;

In the food industry, cleaning equipment for equipment cleaning and material agitation;

In the automotive industry, it can be a cleaning device for car cleaning tools;

In life, it acts as a dredge for constructing the residential community and a cleaning device for the sanitation road.

Advantage:

1. Use high-quality magnetic materials to ensure sufficient output power, small working current, effectively reduces temperature rise, good heat dissipation, and high efficiency.

2. high-quality bearings and rigid assembly 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 gear, and worry-free operation.

Protection

hollow shaft motor is IP-44 protection as defined in IS:4691 Motors can be supplied with IP-54 and IP-55 on request

Insulation

Hollow shaft motors supply with class B&F insulation as a standard feature.

Terminal Box

all three-phase motor supply with a terminal box on top for Foot mounted. Other position boxes like left or right supply on customer request.

Shaft

Hollow shaft motor shaft made from high carbon steel pipe to provide exceptional strength&rigidity to minimize deflection. we can also supply the motor with stainless steel hollow shaft

Rotor

All hollow shaft motor rotors are of high-pressure E.C. Grad aluminum die-cast. Every rotor is dynamically balanced. Thus, it makes low motor amplitudes of vibration & noise.
