Magnetic actuator |
摘要 |
A bistable permanent-magnet actuator is disclosed having a tailored switching/position force characteristic, with an adequate, modifiable holding force in the end positions. The actuator is characterized in that the yoke is formed by two parts that are mounted so as to face each other and are separated by two gaps. The dimensions of the air gaps may be tailored to obtain intended characteristics.
