A compressor provided with a motor includes several core block assemblies aligned in the circumferential direction of a bobbin and the several core block assemblies have a V-shaped bending shape.

A method includes forming elongated magnetic flux carrier portions in magnetically conductive sheets by cutting elongated magnetic flux barriers including one or more relief features into the magnetically conductive sheets, such that the magnetic flux barriers are separated from each other in radial directions of the magnetically conductive sheets. The method includes inserting or forming non-magnetic posts into the magnetic flux barriers such that each of the non-magnetic posts is elongated in a different radial direction of the radial directions from a first magnetic flux carrier portion to a second magnetic flux carrier portion of the magnetic flux carrier portions on opposite sides of at least one magnetic flux barrier; and forming at least part of a rotor for an electric machine assembly using the magnetically conductive sheets having the magnetic flux carrier portions, the non-magnetic posts, and the magnetic flux barriers.

A flat-type effect module includes a first flat motor and an effect wheel assembly. The first flat motor has a first stator to generate a magnetic field when energized, and a first rotor arranged outside the first stator in a sleeving mode. The effect wheel assembly is fixed to the first rotor, and the effect wheel assembly includes a wheel body for generating a light effect which is provided with effect areas for intercepting a light beam to change the color and/or shape thereof. According to the present invention, no rotating shaft, such as the traditional rotating shaft motor has, exists on the first flat motor, the effect wheel assembly in the present invention is directly fixed to the first rotor, so that the height of the rotating shaft can be reduced and more effect elements can be arranged.

A stator defines multiple stator poles with associated electrical windings. A rotor includes multiple rotor poles. The rotor is movable with respect to the stator and defines, together with the stator, a nominal gap between the stator poles and the rotor poles. The rotor poles includes a magnetically permeable pole material. The rotor also includes a series of frequency programmable flux channels (FPFCs). Each FPFC includes a conductive loop surrounding an associated rotor pole. The stator and the rotor are arranged such that the electrical windings in the stator induce an excitement current within at least one of the FPFCs during start-up.
