Hollow Shaft Motor

Hollow Shaft Electric Motor Description

Hydraulic Electric Motors are a combination of an exceptional degree of technology and innovation, quality and reliability worthy of a leading brand on the market. This Hollow Shaft Electric Motor easily mounts to plunger pumps with a 24mm solid shaft & 1,750 RPM - no coupling needed!

The hollow shaft series motors comply with the relevant regulations of the International Electrotechnical Commission (I.E.C.) and use high-quality raw materials for the latest overall design. The hollow shaft motor casing is made of aluminum, hollow metal tube design, 100% copper coil, C&U bearing, high-precision rotor, shaft extension through high-frequency quenching treatment, significantly improving mechanical strength, rigorous transfer technology, maintaining the standard motor all technical and maintenance advantages are following I.E.C. standards.

Advantage:

1. High-quality materials, low power loss, low current, low-temperature rise, good heat dissipation, high efficiency, and energy-saving.
2, high-quality bearings, rigorous assembly process, low operating noise.
3. Tailored for professional equipment, the shaft extension is processed by high-frequency quenching, which significantly improves the mechanical strength and seamlessly connects with professional equipment to realize worry-free operation.

Frame
