摘要： One disclosed motor includes winding leg and yoke laminations that form a core yoke section and a core winding leg (or coil core). An excitation coil is supported on the coil core; and the coil core and core yoke are relatively oriented so that a first surface of the original strip material faces one direction in the core yoke section, and an opposite direction in the winding leg section in a finished motor. The geometrical configuration of the laminations prevent a random location of winding legs relative to yoke laminations, and yet permits two distinctly different relative lamination orientations. A longitudinal reference line along the winding leg is identified and keying or interlocking means are symmetrical about the reference line, but a winding accommodating portion of the winding leg is asymmetrical about the same reference line, so two distinct winding window openings may be provided, depending on the orientation of the winding leg.

摘要： A two-pole off-set construction of an electric motor has winding portion laminations and rotor portion laminations which are separate so that the winding may be formed or placed on the winding portion and then the two portions of the stator interconnected to complete the flux path for the rotor circumscribed by a rotor aperture in the rotor portion. There must be a window space between these two portions to accommodate the winding on the winding portion and formerly the metal removed from this window space was scrap metal, necessitating an excessive amount of steel lamination material. In this invention, the layer of lamination is made in two complementary pieces and this layer has a rotor portion and a winding portion. The two separate lamination pieces for a layer of complete lamination are to permit the winding to be placed on this complete stator. The material removed from the window space instead of being scrap is utilized as an active flux carrying member by being unitary with one of these first and second lamination pieces. In a first embodiment of the invention the legs joining the end areas of the winding and rotor portions are off-set in the direction toward the winding portion by approximately one-eighth of their length resulting in the bight of the rotor portion, which contains the rotor aperture, being displaced in a direction opposite to the leg extensions. Accordingly, laminations for only the rotor portion are successively formed from a strip of lamination material with the bight of the rotor portion extending into the space between the two legs of the next adjacent rotor portion lamination in the strip of lamination material. In a second embodiment of the invention the rotor and winding portions are unitary on a first piece of the lamination and complementary with a small second piece of lamination. The first pieces of the lamination are nested or interlocked together as they are formed from the lamination steel, utilizing the window space of one piece as the winding portion of the adjacent first lamination piece. This utilizes lamination material from the window space which would otherwise be scrap and saves approximately one-eighth of the steel used in making the motor. The winding portion or second piece laminations are separately made adjacent to each other in a strip of lamination material. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

摘要： A motor comprises an enclosure, a stator and a rotor, the stator comprising a first electromagnetic group and a second electromagnetic group between which the rotor is inserted, the rotor comprising a rotating shaft and a magnetic part installed around the outer wall of the rotating shaft, the motor further comprising an elastic element with a first contact part fixed on rear cover of the enclosure and a second contact part connected with the rotating shaft, wherein the elastic element is elastically deformable in at least two different directions. The motor is applicable to electric toothbrushes, shavers, loudspeakers, electric hammers, stirrers, refrigerators, sewing machines, packaging and bundling machines, electromagnetic pumps, etc. A rotating shaft of the electric toothbrush using the motor has the effects of high-frequency shimming and high-frequency knocking vibration, and the dental calculi on the dental surface are crushed via high-frequency knock, with higher cleaning effect.

摘要： An electric motor including: a frame; a rotor assembly including a magnet, a bearing assembly, an impeller, and a shaft; and a stator assembly including a stator core and a bobbin. The frame has an inner wall and an outer wall, the outer wall surrounds the inner wall and defines an annular channel between the inner wall and the outer wall, and diffuser vanes extend from the inner wall to the outer wall through the annular channel. The inner wall defines a bore for supporting the rotor assembly, and the outer wall defines a substantially cylindrical outer casing of the motor.
