摘要： A linear actuator (10) for use in a modular assembly of such actuators comprises an actuator body (11), a shaft (12) guided by the body to be displaceable relative thereto in the sense of the longitudinal axis (13) of the shaft and a drive motor enclosed in the body and operable to axially displace the shaft relative to the body in two mutually opposite directions. The body has two mutually opposite sides (15a, 15b) respectively lying in two substantial parallel spaced-apart planes, which each represent a reference plane for positioning the body side-by-side with the body of another such actuator, and a further side (17b) connecting the two mutually opposite sides and stepped to form a projection (18) receiving the shaft (12) with the axis (13) parallel to the two planes and a rebate (19) beside the projection to permit the body to interlock with the body of another such actuator at that further side. The projection (18) and rebate (19) are of substantially the same width in the sense of the spacing of the two planes and the shaft (12) is disposed substantially centrally of the projection (18) so that when the body (11) is interlocked with that of another such actuator the pitch of the shaft axes (13) is equal to that width.

Each of the multiple stator units includes a stator, a winding, a photoelectric switch, a reading head, and a driver. Each of the multiple mover units includes a mover, and a magnetic steel, two stoppers, and a grating ruler. Each of the two stoppers are configured to pass and block the photoelectric switch. The grating ruler is arranged opposite to the reading head, and the reading head is configured to read information from the grating ruler in real-time. The controller is configured to obtain the reading signal and two zero signals from the photoelectric switch by the driver. Compared with the conventional art, the multi-mover direct drive transmission system of the present invention has simple structure, high positioning accuracy, and easy to use.

摘要： A mechanically commutated motor (200) configured for use with an external magnetic field (240) is disclosed. The motor (200) includes an axle (208) formed of anon-magnetic material. A rotor (206) is coupled to the axle (208), the rotor (206) including three or more actuator units (205) spaced about the axle (208). Each actuator unit (205) comprises a non-magnetic material, a coil winding (214) along each of the three or more actuator units (205), and a commutator (216) coupled to the axle (208) and electrically associated with the coil windings (214). The motor (200) further includes two or more resilient contacts (210) oriented to direct a current through the commutator (216) to one of the coil windings (214) to induce a current in the coil winding (214) to form an electromagnet that rotates the rotor (206) relative to the external magnetic field (240) from a magnet located external to the mechanically commutated motor (200).
