摘要： The disclosure relates to a vehicle lock having a locking mechanism, a lock mechanism and an electrical setting arrangement, wherein the setting arrangement has a rotor arrangement, and a stator, wherein the stator forms at least two magnetic, unlike stator poles of the stator magnet arrangement, wherein at least one of the magnet arrangements is associated with a coil arrangement, wherein by supplying current to the coil arrangement and a resulting magnetic interaction between rotor and stator, a drive torque to the rotor and thus an adjustment of the rotor can be generated in a predetermined number of actuator positions. Proposed is that the rotor magnet arrangement and the stator magnet arrangement are stationarily fixed to a support section of the motor vehicle lock, and the rotor is pivotable about a rotor axis relative to the support section and relative to the rotor magnet arrangement.

摘要： A linear fan including a fan blade attached a fan frame by a wire spring having a first end attached to the fan blade and a second end attached to the fan frame. The fan blade includes a free end such that the blade oscillates by pivoting on the wire spring. The the wire spring flexes to enable the fan blade to oscillate. The fan includes a motor for driving the oscillation of the fan blade. The motor includes an armature or permanent magnet connected to the fan blade and a stator assembly connected to the fan frame. The stator assembly includes a current carrying coil wrapped around a leg of a stator core. The motor is controlled to vary the direction of the current being carried in the coil to thereby change the direction of the magnetic field created by the stator assembly and cause the fan blade to oscillate.

摘要： An engine includes an engine block with at least one cylinder bank including cylinder bores formed therein. A piston is reciprocatingly disposed in each of the cylinder bores. A crankshaft is rotatably mounted to the engine block. Connecting rods are rotatably attached to the crankshaft and are coupled to the piston. A cylinder head with intake valves and exhaust valves in fluid communication with the cylinder bores is mounted to each cylinder bank. At least one permanent magnet is disposed in a skirt of each piston. At least one electromagnet is positioned adjacent to the permanent magnet(s). A control system selectively provides an electrical current to the electromagnets to produce a desired magnetic field, wherein the magnetic field of the electromagnets cooperates with a magnetic field of the permanent magnets to affect a motion of the piston in respect of the engine block.

摘要： A vibration motor having an insulating housing, a bidirectional coil and a magnetic ring is provided. The insulating housing is of cylindrical shape and at least three position-limiting ribs are protruded from an internal surface thereof. Each position-limiting rib is extended parallel to a central axial line of the insulating housing. The insulating housing has a pair of end plates on two ends thereof. The end plates are made of insulating material. The bidirectional coil is accommodated in the insulating housing and spaced apart from the internal surface of the insulating housing. The magnetic ring is movably accommodated in the insulating housing, and the magnetic ring is arranged coaxially with the insulating housing to surround the bidirectional coil. The position-limiting ribs are disposed adjacent to the magnetic ring and surround an outer edge of the magnetic ring.
