High Voltage Motors

High Voltage Motors with Squirrel cage rotor or slip ring rotor will be build for nominal voltage 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.

High-voltage motors will be build with the following standard
configurations:

IM B3 configuration for horizontal installation
IM V1 configuration for vertical installation
For special mounting arrangement please contact us or
use our detailed order sheet!

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)

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 %
