The simple way of controlling machine and plant speeds economically: 2-speed motors. We offer pole-changing DR.. series AC motors with a power combination from 0.15 kW / 0.20 kW to 18 kW / 34 kW. With this large selection, you are sure to find the suitable motor for your application.

2 speeds with a ratio of 1:2 or 1:4
We supply pole-changing 2-speed AC motors in sizes and designs DR63 and DRS.. as 4/2 and 8/4-pole motors with speeds in a ratio of 1:2 and as 8/2-pole motors with speeds in a ratio of 1:4 (DRS.. only).

These motors also come from our modular system – take advantage of its benefits: for example, we offer pole-changing AC motors for countries with a 50 Hz or 60 Hz line frequency, with the required voltage of course. Our pole-changing motors naturally come with all the certifications required by international regulations, so you can use them anywhere in the world, for example in Canada (CAS certification), the USA (UR certification) or in China (CCC certification).
