An electric device has a driveshaft with at least one stator cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the stator cylinder is parallel with but spaced apart from the driveshaft axis. A magnet assembly is disposed in each end of the stator cylinder, with one magnet assembly engaging one cam and the other magnet assembly engaging the other cam. Each magnet assembly includes a cam follower that can move along a curvilinear shaped cam. A magnet slide arm attached to the cam reciprocates magnets carried on the magnet slide arm through electromagnetic windings disposed around the stator cylinder. An electrical input delivered to the windings can reciprocate the arm, driving the cams to rotate the driveshaft. Alternatively, rotation of the driveshaft can be used to reciprocate the arm to induce electric current in the windings.

A linear actuator comprises a motor for producing a bi-directional rotational output. A casing is connected to the motor at a proximal end, the casing having an inner cavity defining a joint surface. A shaft is within the inner cavity of the casing and actuated by the motor for rotation. A sliding tube is at least partially in the inner cavity of the casing for moving in translation in an axial direction relative to the casing. One or more travelling nut is connected to the sliding tube assembly for moving with the sliding tube in the axial direction, the travelling nut being operatively engaged to the shaft for converting a rotational motion of the shaft into a translation of the sliding tube. A liner is between the sliding tube and the joint surface of the inner cavity, an inner surface of the liner defining longitudinal contact surfaces separated by longitudinal grooves, the longitudinal contact surfaces contacting the sliding tube.

An electronic brake motor structure includes a lower housing coupled to a block; a ball screw installed in the center inside the housing and block; a nut member into which the ball screw penetrates to be coupled therewith; a piston coupled to an outer side of the nut member; a hollow shaft coupled to an outer side of a lower part of the piston; a rotor module including a rotor and a magnet, coupled to an outer side of the hollow shaft; a stator module coupled to an outer side of the rotor module; an upper bracket for mounting a first bearing to thereinside; a driven shaft, coupled to an upper part of the ball screw to support the ball screw; a joint member coupled to a bottom of the ball screw with a mounting bolt to support the ball screw and a fourth bearing.

An actuator includes a cylinder sandwiched between a fixing plate fixed to the other end surface of a supporting plate together with a servomotor and a bearing housing, a ball screw shaft having one end protruding into the cylinder through through holes of the fixing plate, a slide block screwed with one end of the ball screw shaft in the cylinder, a cylindrical-shaped piston coupled to an end of the slide block and reciprocatably located in the cylinder, linear motion bearing units located inside the bearing housing to movably support the piston, and linear motion bearing units located in the cylinder to movably support the slide block.

A vehicular exterior door handle assembly includes a base portion disposed at a handle region of a vehicle door, a handle, and an actuator. The actuator includes an electrically-operable motor, an output element mechanically coupled to the handle, and a variable drive element coupled to the output element. When the motor is operated, the actuator causes the drive element to move the output element and move the handle from a recessed position to a deployed position. When moving the handle from the recessed position, the drive element moves the output element at a first speed to move the handle. When the motor is operated to further move the handle, the drive element moves the output element at a second speed to more rapidly move the handle from a partially deployed position toward a deployed position.

A first sensor signal and a second sensor signal are provided by a sensor unit to an evaluation unit. The first sensor signal is dependent on the angular position and is associated with a first detection position, and the second sensor signal is associated with a second detection position lying about the rotational axis perpendicular to the first detection position. An angular position of a rotational component is determined by the evaluation unit based on output from an atan2-function that takes the first and second sensor signals as input. A harmonic error is determined by the evaluation unit based on a periodic error signal that is superimposed on each of the sensor signals. An angular error of the angular position is determined by the evaluation unit based on the harmonic error. The angular position is updated by the evaluation unit based on the angular error.

An adjustment drive for a motor-adjustable steering column for a motor vehicle, includes a spindle drive having a threaded spindle which engages in a spindle nut which, so as to be able to be driven in a rotating manner about the spindle axis relative to the threaded spindle, is coupled to the rotor shaft of a drive motor which has a rotor and a stator. In order to enable a compact design with minor complexity, the rotor shaft of the drive motor is configured as a hollow shaft which is disposed so as to be coaxial with the spindle axis and in which the threaded spindle is coaxially disposed.
