Pressurized synchronous motors

Equipment protection level Gb and Gc for zones 1 and 2

ABB offers a wide range of synchronous motors for variable or constant speed applications. Our motors are tailor-made within a standard design to meet customer-specific needs, application requirements and grid characteristics. High performance and cost efficiency are achieved through optimal utilization of active materials.

ABB has a long track record in supplying synchronous motors for all types of applications to customers all over the world. The design and performance are constantly updated to include new technologies and field experience. Our global service network and predefined maintenance programs ensure support for all life cycle stages of ABB motors.

The design of ABB synchronous motors with Ex px and Ex pz protection type is based on pressured and purged enclosure. The purging pressure is supplied by a purging system included in the motor design.
