Rotary drive with straight primary part segments

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.

主权项

1. An electric drive for performing a swiveling or rotary movement, comprising:
a secondary part having a circular or arc-shaped configuration; and a primary part having at least one primary part module arranged on one side of the secondary part and shaped on the one side in the form of an arc, said primary part module having at least three straight primary part segments which are arranged at a predetermined angle with respect to one another corresponding to a shape of the secondary part in relation to their longitudinal directions, the straight primary parts segments are configured as straight linear stators which are linear motor components and have a straight, parallelepipedal shape, and each of the at least three primary part segments can drive in a circle with a diameter corresponding to the circular or arc-shaped configuration of the secondary part.
