摘要： The aim of the invention is to provide pivoting and rotary drives for electric machines with low number of parts economically. Said aim is achieved, by means of a secondary part (4) of circular or arched design. The primary part of the drive has at least two straight primary part segments (1), arranged at a predefined angle to each other in the longitudinal direction thereof to correspond to the shape of the secondary part (4). A pivoting or rotary drive can thus be economically produced with standard linear motor components.
