ELECTRICAL MACHINES, DRIVE SYSTEMS AND SYSTEM ENGINEERING Range of Supplies and Services
Quality – the basis of confidence
Schorch Elektrische Maschinen und Antriebe GmbH has
introduced a Quality Assurance System in accordance with
DIN EN ISO 9001. This was confirmed by DQS for the first
time in 1993.
In March 1999, Schorch was certified as a manufacturer of
three-phase asynchronous machines to type of protection
Increased Safety ’EExe’, Flameproof Enclosure ’EExd’, and
Pressurized Apparatus ’EExp’ by a PTB certification audit.
In July 2001, our Quality Assurance System was certified
by DQS again, this time in accordance with the new DIN
EN ISO 9001 (Issue 12.2000).
Since the foundation of the company in 1882, the name
SCHORCH has always stood for high-quality electrical
machines. With numerous drive systems and installations
supplied worldwide, SCHORCH is the competent partner
for your international projects.
SCHORCH is a modern, market-oriented supplier of a
variety of industries, e. g. the chemical/petrochemical
industry, power generation and distribution, water supply
and waste water industry, metal producing and processing
industry, etc. This means that our products have to meet
the requirements of a wide range of applications in view of
both quality and reliability.
We supply asynchronous machines with outputs up to
25,000 kW. Our range also includes the design and supply
of complete drive systems and installations, and a
comprehensive service.
On request, we supply motors from our production range
with AEG-rating plates.
Our aim is the design and construction of state-of-the-art
products which meet all economical, technical and eco-
logical requirements.
Our machines, drive systems and installations are
characterised by innovative technology combined with the
highest possible quality standard. The quality of our
products is certified to EN ISO 9001. Our strength is,
however, not only technical quality – based on more than a
century’s company tradition – but also a well-founded
competence in designing and planning, the sum total of the
abilities of our highly skilled and motivated workforce.
Electrical Machines, Drive Systems and System Engineering

Available for indoor and outdoor installation to various
degrees and types of protection. These machines are
characterised by high efficiency and low noise level, and
are fitted with short-circuit and shatterproof terminal boxes.
Windings are insulated, using the well-known VPI system.
By means of various attachments, these machines can be
adapted to almost any application. Designs for difficult and
severe site and operating conditions, both conventional
and explosion-protected, are also available.
The range includes surface-ventilated motors with ribbed
frame, tube-cooled and modular design motors, all of
which are available with the customary cooling methods
and degrees of protection. In the development of these
motors special emphasis was laid on high efficiencies, low
noise and vibration levels, ease of maintenance and long
service life. This is ensured by a sturdy design with a high
degree of adaptability to various applications.
