Custom high-voltage compressor motor extra-light
An extra-light high-voltage motor for a refrigeration compressor in Germany was recently inquired at the German motor manufacturer MENZEL Elektromotoren. The new 6000V compressor motor was a custom-made and used as a backup motor in the field of industrial refrigeration solutions.
MENZEL serves industrial customers worldwide and has already supplied numerous compressor motors in the medium and high-voltage range for industrial refrigeration systems. In the case of the refrigeration compressor in Germany, an extremely lightweight squirrel cage motor was required. The new motor is 1: 1 interchangeable with the existing high voltage motor and was not to exceed the maximum permissible weight at its final destination.
Custom-made HV compressor motors
In order to meet the customer's request, some adjustments were made on the new HV compressor motor. For example, a special housing makes the 6000 V squirrel cage motor extra lightweight due to its choice of materials. In addition, the option of IC 81W water cooling compared to an air heat exchanger has a positive effect on the total weight of this HV compressor motor.
Another customization was the cable entry. Cables are inserted laterally into the terminal box. The 2-pole replacement motor type MEBKSW400-02 has a nominal power of 1044 kW and a speed of 2980 min-1.
As long-time German motor manufacturer, we specialize in the customization of electric motors for industrial applications of all kinds. Our engineering team is happy to advise you!
Compressor motors for refrigeration systems
MENZEL supplies individual compressor motors for refrigeration systems from 315 to 20000 kW. The motors are available in a wide variety of sizes and cooling types. They offer optimum performance, maximum reliability, and a particularly high level of efficiency.
Compressor motors run at very high speed with high performances. To minimize the resulting vibrations, the balancing quality of these motors must be particularly high. At high speeds, the use of slide bearings also offers smoother motor operation - as in the present case of the refrigeration compressor.
MENZEL squirrel cage motors are standard equipped with grease-lubricated rolling contact bearings, and include a re-lubricating device. Models with self-lubricating or separately lubricated sleeve bearings are available upon request. At MENZEL only high-quality bearings and lubricants from well-known manufacturers are used.
MENZEL works and produces according with the strictest quality specifications, which are regularly tested and certified by TÜV. Menzel Elektromotoren Berlin is TÜV certified pursuant to DIN EN ISO 9001.

High voltage test in our Berlin load test field
The final type and high voltage test of the squirrel cage motor was carried out in our in-house load test field in Berlin in the presence of the customer. The MENZEL load test field is one of the most modern test systems of its kind in Germany.
Our load test field team offers comprehensive testing services around routine, type and system tests. The offer also applies to external clients and makes. Facilities include amongst others a 6 kV inverter, rotary converters for all common voltages from 3 to 13.8 kV and load resistors for testing generators.
