Actuator for use in motor vehicle to adjust e.g. heating, ventilating or air conditioning damper, has sensor e.g. inductive sensor, directly coupled with output wheel, and determining exact position of condition of output

摘要

The actuator has a sensor e.g. inductive sensor, directly coupled with an output wheel, and determining an exact position of the condition of an output. A form memory alloy (1a) is designed as electrical voltage dividers. The limitation of a linear movement or the angle of rotation of the output is made by a mechanical impact, where the actuator is provided with a spur gear, planetary gear, and Harmonic drive. The sensor determines the length variation of the form memory alloy.
