The EMCA combines a wear-free EC motor, power electronics with position controller, optional holding brake and fieldbus connection in a compact housing concept. A modular product system provides the attachment of various gear units. Cleverly thought-out connection technology as well as high protection classes against water and dirt make it ideal for industrial use. The design underlines the compactness and provides the framework for the entire unit. Intuitive operation by the user is supported with a clearly defined connection area.
