Electric motors ABB series DMI They have a high specific power, advanced speed settings and high structural strength. Optimized anchor design, high-quality support elements, the collector assembly has an elongated brush design for a longer service life of these consumable elements, a mechanical wear control system is implemented. A great combination of outstanding performance and reduced maintenance levels.
The low-profile rectangular design makes it possible to integrate motors as conveniently and compactly as possible, even into already formed drive systems. They are universal in relation to industry applications, a wide range of design modifications and additional options are presented to adapt to various factors of the working environment.
