H-compact in low-voltage version
Maximum power - minimum size – especially for converter operation

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 (low-voltage) - 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 copper cage for a high degree of reliability and low additional losses (exception: aluminium die-cast cage for shaft height 450, 4- to 8-pole)
• 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 (thermal class 155, previously temperature class F) guarantees a high degree of reliability and a long lifetime.
• Approved Durignit® IR 2000 insulation system for shaft height 450, 4- to 8-pole.
