ABB designs electric motors for reliability and high efficiency to help reduce energy consumption and eliminate breakdowns - saving time and money
ABB believes it is important to produce quality motors with reliable, high efficiency design to reduce energy costs, eliminate breakdowns and ultimately save money for customers. ABB continues to develop and invest in a better product with even higher levels of performance.
ABB’s ‘Process Performance’ motors are particularly suited to demanding 24/7 operations, where end users cannot afford the loss of production through breakdowns.

ABB motors are globally renowned for market-leading efficiency, reliability and longevity.
Innovation
The low voltage Permanent Magnet (PM) motor is a new type of synchronous motor designed for low speed applications, using a variable speed drive. While similar in construction to the robust induction motor, it matches the accuracy of the traditional synchronous motor.
Its simplified design uses powerful permanent magnets to create a constant flux in the air gap, eliminating the need for the rotor windings and brushes used in synchronous motors. This means the PM motor can deliver very high torque from a small motor size at low speed, eliminating the need for gearboxes.
With fewer components, the PM motor is more reliable, it takes up less space, is easier to install, and requires less maintenance and fewer spare parts than other low speed motor options. But more importantly, it delivers accurate and efficient speed control, from 100–850 r/min, in a smaller, lighter unit.
PM motors are used to power low-speed pumps, in wind and water-driven power generators, paper machine drives, low speed fans, elevators and in many other applications.

In 2004, the ABB Motorformer received the Control Engineering Editor’s Choice award in recognition of the product’s service to industry, technological advancement and market impact.
Innovation
Unique to ABB, the Motorformer is a very high voltage motor or generator suitable in any application where conventional synchronous machines are used. Operating at very high voltages up to 70kV, it can be connected directly to the grid, with no need for a transformer or secondary side switchgear. Its stator windings consist of standard XLPE-insulated power cables that are circular in shape, allowing for smooth field distribution around the conductor.
With no need for a transformer and switchgear, the ABB Motorformer is more efficient, has a smaller footprint, is faster to install, reduces energy loss by up to 25 percent, and requires less maintenance than the conventional synchronous motor system. A superior life cycle cost generates bottom line savings for ABB customers.
