Crane Drives

Robust and reliable - AEM crane motors

The transition from DC technology to the modern age of power electronics created new challenges for three-phase machinery, and in particular for speed-controlled three-phase motors with cage rotors. We developed robust motors as crane drives for numerous applications, including for the port, shipping/offshore and steel industries. These applications require special construction, as well as the electrical design of the machinery. The tried-and-tested technology of using slip-ring motors as crane drives is increasingly in demand. The machines carry out heavy starts without any negative effect on the rotor winding and are highly suited to operating modes such as S3. AEM crane motors are inspected and approved by shipping classification societies and can therefore be used in both marine and offshore installations.
