GH 225-630 type machines are designed to meet and exceed
the rigorous performance requirements of industrial applications.
Their exemplary electrical and mechanical designs assure flawless
operation in the most severe, heavy duty service.
All stator cores contain high performance electrical steel
laminations, with compensating windings provided in main poles.
The standard winding insulation system employs Class H materials,
but standard performance is limited to Class F temperatures to
extend machine life. Where required, size GH 225 can be supplied
without compensation.
Mechanically, modular components are featured to allow the
greatest flexibility to meet Customer’s varied needs.
GH four-pole series of motors utilizes frames having seven shaft
axis heights: 225, 250, 280, 315, 355, 400, and 450 mm.
GH six-pole series covers three shaft axis heights: 500, 560,
and 630 mm.
While the usual mounting arrangement is horizontal foot mounted
(IM B3 [code I] or IM 1001 [code II] in accordance with EN 60034-7)
alternate arrangements are available on request. The factories
are equipped with up-to-date machinery and modern
manufacturing techniques for the production of the highest quality
interchangeable parts.
The motors described in this catalogue cover a range of power
output from 160 kW at 1500 rpm (1,019 kNm) [GH225SK] to
1800 kW at 500 rpm (34,38 kNm) [GH630ZK].
