H-compact PLUS
The synthesis of a compact motor design and modular cooling

Highest power rating, reliability, efficiency and modular cooling system: This distinguishes the three-phase high-voltage motors of the H-compact PLUS series.

These motors are available in shaft heights 450, 500, 560 mm with a gray caste iron enclosure, as well as 630 and 710 mm with a steel enclosure in degree of protection IP 55 or IP 23 - air or water cooled.

The insulation and bearing system guarantees the highest degree of reliability.
The MICALASTIC insulation system with VPI impregnation offers high switching and reversing strength and has proven itself worldwide even under the toughest of application conditions: In extreme cold, heat, humid and aggressive environments.

The lifecycle costs are extremely important – and these make the H-compact PLUS motor so attractive.
H-compact PLUS motors save energy, require little maintenance and operate reliably over their long motor lifetime. An investment that pays back in a short time. H-compact PLUS motors are environmentally-friendly and can be recycled up to approx. 98%
