Using a modular design-and-build principle, each component and each design detail of an ABB high voltage modular induction motor are engineered and manufactured to maximize motor performance and provide a uniquely low cost of ownership over a long and productive operating life.

Bearings

The bearings used by ABB are designed for a reliable, continuous service life of more than 100,000 hours, and for ease of maintenance. The motors are fitted with SPM nipples and grease valves as standard, and are tested at up to IP 56 protection against dust ingress and water. ABB also offers a broad range of bearing options, including spherically seated self-aligning sleeve bearings, thrust bearings, and special bearings such as cylindrical roller bearings and deep-groove ball bearings. All bearings have a sealing system that prevents dust penetration.

MICADUR® Compact Industry insulation system
In ABB’s Micadur® Compact Industry insulation system, a specially formulated epoxy resin has been used to insulate all its rotating electrical machines over the past 30 years. Micadur ® ensures a sealed and homogeneous insulation system, resulting in low dielectric losses, high dielectric strength, excellent heat transfer and the elimination of hazardous internal partial discharges. As standard, all motors are designed to stay within temperature
Class F.

Cooling system
Efficient cooling is vital for peak motor performance in all ambient operating conditions. ABB offers a variety of symmetrical and asymmetrical cooling systems to match operational requirements. They range from weather-protected open ventilated systems to totally enclosed systems fitted with air-to-air or air-to-water coolers.
