FIELD: mechanical engineering.
SUBSTANCE: electromechanical lock utilizes magnetic field forces at the stage of moving the actuator from the locked position (260) to the open position (400) under the impact of electrical energy. In the locked position (260), the permanent magnet arrangement directs (1204) the magnetic near field to block the rotation of the access control mechanism, while at the same time, the permanent magnet arrangement weakens (1206) the magnetic near field in the direction of the magnetic far field of breach coming from the outside of the electromechanical lock. In the open position (400), the permanent magnet assembly directs (1208) the reverse magnetic near field to release the rotation of the access control mechanism, while at the same time, the permanent magnet assembly weakens (1210) the reverse magnetic near field in the direction of the magnetic far field of breach.
EFFECT: improved breach resistance of an electromechanical lock with simplified mechanical structure of the electromechanical lock.
