Abstract
A drive unit for a machine comprising a plurality of linear motors, which are disposed parallel to each other in a common direction of feed, the parts of the linear motors with the same action being interconnected for common displacement, wherein the linear motors include magnetic elements in the direction of feed and coil elements communicating therewith, wherein at least one power unit is associated with the linear motors, wherein force determining means are provided for determining the path-dependent force of the linear motors at least during assembly or commissioning and in that, in the operating state, a controller regulates, to a required characteristic, the power which is supplied to the linear motors by the power unit in dependence on the force, which is dependent on the path position of the linear motors and is determined by the force determining means.
