Motor for compressors

Custom design of IM B5 squirrel cage compressor motor with support foot

When the existing compressor drive with extra support foot failed in an industrial plant in France, MENZEL was able to quickly help with a custom design of a new IM B5 squirrel cage motor. The very constricted space conditions in the compressor required the most accurate adjustment measures.

For example, a special flange for the new squirrel cage motor was lathed at our Berlin motor factory within only a few days. At the same time, special threads were provided for the support foot and the terminal box was brought to the same position. This allowed the customer to quickly and easily install and commission the new motor.
