Unification of equipment and industry specialization are the foundations of the success of Siemens, in whatever industry its products are presented, they occupy a leading position. DC motors 1GG7 /1GH7/1HS7/1HQ7 are no exception, they are the best on the market in terms of their performance characteristics.
The limited power range from 200 to 1000 kW is due only to the fact that only in this range it is economically justified to use DC electric machines when operating in constant peak and cyclic loads, for a range up to 200 kW, Siemens offers to use asynchronous and synchronous electric drives, for a range from 1000 kW - high-voltage equipment. Adhering to the corporate principle - the absence of internal competition between product departments, allows Siemens to use its full technical potential only to create unique economically sound equipment.
High power density, increased efficiency, perfect switching, low noise, highly reliable DURIGNIT 2000 insulation system, optimized electromagnetic and mechanical characteristics are what distinguishes Siemens DC motors of the 1GG7 /1GH7/1HS7/1HQ7 series from other electric machines. These electric motors find their application both in the production of new technological equipment and in modernization, the main areas of application are mills, crane equipment, rolling mills, paper machines, presses, extruders.
