Abstract
An electromagnetic braking assembly for maintaining an actuator shaft in position, and methods for utilizing the same, are provided. The actuator shaft may include an object, e.g., an imaging lens, which is movable in accordance with movement of the shaft. The braking assembly may include a braking coil to which electricity may be applied to produce a magnetic field, a braking magnet capable of changing position as it interacts with the magnetic field, and a braking spring coupled with the magnet such that the spring changes position as the magnet changes position. When the braking spring is in one position, the spring exerts pressure on the actuator shaft substantially preventing the shaft from engaging in linear movement and thus maintaining the shaft in position. When the actuator shaft is in another position, the braking spring does not exert pressure on the shaft permitting the shaft to engage in linear movement.
