Aluminium 3 Phase Asynchronous Motor 230V/400V 4 Pole 71 Frame B35 IE1 Efficiency

IE1 Aluminium Three-Phase Hollow Shaft Motor 230V/400V 4 Pole 71 Frame B35

Hollow Shaft Motor

The hollow shaft motor consists of a stator and a rotor end cap. It is designed with a hollow metal tube. It is a new type of motor with an internal joint designed for high-pressure pumps. It reduces the overall size of the hollow shaft and maintains all the technologies of the standard motor. Maintenance advantage. It is adopting new technology design, 100& all-copper coil, C&U bearing, shaft extension through high-frequency quenching treatment, significantly improving mechanical strength, with low-temperature rise, fast heat dissipation, high efficiency, and energy-saving. It is connected to the pump for high-pressure water column cleaning.

Application

hollow shaft motor is widely used in below:

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 as 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. the use of high-quality bearings, rigorous assembly process to achieve low noise operation.

3. tailor-made for professional equipment, shaft extension through high-frequency quenching treatment, significantly improve the 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. Also, supply on request of the customer.

Terminal Box

all three-phase motor supply with a terminal box on top position 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.
