We stock and build high-voltage motors, squirrel cage or slip ring, normally for nominal voltages between 3 KV and 11 KV. Custom constructions deviating from these specs are possible for up to 13.8 KV in nominal voltage. Standard frequencies are 50 and 60 Hz.

We build high-voltage motors with the following standard configurations:

IM B3 configuration for horizontal installation
IM V1 configuration for vertical installation

Custom configurations are possible; for details, please contact our plant in Berlin.

Standard types of cooling systems:

IC 411 (ribbon-cooled)
IC 611 (using air-air heat exchanger)
IC 81 W (using air-water heat exchanger)
IC 01 (open circuit air-cooled)

Standard degrees of protection:

IP 55 (fully enclosed)
IP 23 (open construction, open circuit air-cooled, drip-proof, suitable for indoor installation only)

Ambient conditions according to IEC standard (deviations from these, while by all means possible, need to be specified):

Ambient temperature 40°C max.
No direct exposure to sunlight
Relative humidity 80% max.
Installations at elevations of 1,000 m above sea level or less
Voltage stability: ± 5%
Frequency stability: ± 2 %
