Abstract: A lens device comprises a connect assembly, a lens assembly and a drive assembly. The lens assembly is disposed on the connect assembly and has a central axis. The drive assembly comprises a first coil, a magnet and a second coil. The first coil is wound around the lens assembly. The magnet is disposed on the connect assembly and has a first magnetic pole, a second magnetic pole, a first direction of magnetic field and a second direction of magnetic field. The first direction of magnetic field and the second direction of magnetic field are not parallel to each other. The first direction of magnetic field points toward the first coil. The second coil is disposed on the connect assembly. The second direction of magnetic field points toward a part of the second coil.

Abstract: A rotor mechanism includes a plurality of rotor bars and a rotor core. The rotor bars are disposed along the edge of the rotor core. The rotor core has a plurality of magnetic flux-barrier units and at least one flux channel. Each magnetic flux-barrier unit extends from one of the rotor bars to another rotor bar. The flux channel passes through the flux-barrier units and surrounds an axis of the rotor core, wherein each magnetic flux-barrier unit is a magnetic flux barrier, and the area between the adjacent magnetic flux-barrier units and the flux channel are pathways for magnetic flux.
