摘要： A multipole electric motor having a plurality of pole laminations (8-11) guided from ends of coils (4, 5) to a permanent magnet (13) of a rotor (14), the pole laminations (8-11) are firstly produced as a coherent sheet-metal part, and is partially injection-coated with a plastic. Subsequently, the pole laminations (8-11) are separated from one another by means of a laser beam, for example. This renders the mounting of the pole laminations (8-11) particularly simple.

摘要： A C-frame motor having cooperating first and second stack of laminations is disclosed. The first stack of laminations includes an end leg with a spaced pair of side legs which are attached at one end to the end leg and terminate in an opposite end in an outer free extremity. A rotor opening is provided in the end leg of each first stack of laminations. When stacked, the rotor openings of adjacent stacked end legs provide an aligned rotor opening for receiving a rotor. Each of the stacked side legs have a combined predetermined outer cross sectional configuration coil winding area that provides a coil winding area for receiving an electrically conductive coil on each of the stacked side legs. The second stack of laminations is attached to the outer free extremity of the spaced pair of stacked side legs in the first stack of laminations in order to provide a combined magnetic inductor circuit. Each electrically conductive coil is preferably wound about an insulating bobbin which may be integrally connected to another insulating bobbin to facilitate winding of an electrically conductive wire about the insulating bobbins and subsequent mounting of the insulating bobbins over the spaced stacked side legs of the first stack of laminations. Improved methods of manufacturing the first and second stack of laminations from an elongated strip of magnetically conductive material are also disclosed.

摘要： A stator for a fractional horsepower motor has a mounting hole of reduced dimensions for fixing the position of motor mounting brackets which support a rotor. The configuration of the mounting holes increase the area where magnetic flux may pass. One configuration reduces the depth of the mounting hole to one or two laminates of each side of the stator. Another configuration is an elongated hole which lies in the direction of the magnetic flux. Each laminate may have a tang which interlocks with tangs on other laminates when the laminated stack is squeezed together in a punch press.

摘要： A two-pole electric motor constructions are described which have stator winding encircling the rotor, and the method is described of assembling same. A main stator section is provided with coil bearing surfaces which receive rotor coils after the rotor has been inserted into the rotor receiving opening, the coils being moved into overlapping relationship with the rotor and limited in movement or aligned by a stop or limit projection between the coil bearing surfaces. The main stator sections are secured either by the use of U-shaped upper and lower yokes, or rectangular yoke sections to fix the positions of the stator coils, and the rotors are mounted for rotation but against axial movement by the means of suitable brackets or stand-off or spacing members.
