H-compact
Maximum power - minimum size
The increasing significance of energy-saving, environmental legislation, the desire for even smaller dimensions and the demands of domestic and international markets have led to the further development of the H-compact series that has proven itself over the years.
H-compact motors are used in the widest range of industry sectors - such as oil & gas, paper, chemical industry or steel. In these sectors, they are used to drive compressors, blowers, refiners, crushers and air separation systems.
H-compact is available in a version for direct connection to the line supply and in a version for converter operation.
H-compact is also available in an explosion-proof version.
As a result of its innovative technology, H-compact sets new standards for high-voltage motors.

H-compact - Customer benefits
- Optimum efficiency and therefore lower operating costs.
- High power density and compact design result in a lower space requirement and lower weight.
- Additional advantages include the reliable bearing design as well as rotors with aluminum die-cast cage for a high degree of reliability and low additional losses (stray losses)
- The bearings are designed for the highest degree of reliability. In turn, this results in excellent vibrational behavior, longer lifetime and lower service & maintenance costs.
- The MICALASTIC® insulation with VPI impregnation (temperature class F) guarantees a high degree of reliability, a long lifetime and high load capability when faults occur - e.g. when accelerating or under overload conditions.
- The noise level is low therefore complying with the high demands of safety at work legislation.
