Title:
【発明の名称】電磁式回転調整器
Document Type and Number:
Japanese Patent JPH04507328
Kind Code:
A
Abstract:
The aim of the invention is to simplify a rotating actuator (1) with a magnetic reset element (18), in particular for controlling the cross-section of a choke, and to improve the torque profile of the reset element (18). To this end, the reset element (18) is made of ferromagnetic material and is arranged in the region of the permanent magnet segments (10) of the servomotor (2). The reset element (18) catches on the recesses (30) in the permanent magnets (10). This increases the precision with which the element (18) swings into its locking position. The rotating actuator (1) is particularly suitable as an idling rotating actuator in internal combustion engines.
