Abstract: A substantial saving of material cost and weight is obtained in an induction motor by a rotor including two sets of differently punched laminations. The laminations in one of the two groups each weigh less than 95% of the laminations in the other one of the two groups. Such laminations can be automatically produced on a computer-controlled die press by providing a separate punch pattern that is capable of being programmed for selected laminations. The lighter laminations can be used to counterbalance a crank without requiring additional counterbalancing weight to be added outside the motor.
Abstract translation: 通过包括两组不同冲压的叠片的转子在感应电动机中获得了大量的材料成本和重量的节省。 两组中的一组中的叠层每个重量小于两组中另一组中的叠片的95％。 这样的叠片可以通过提供能够被编程用于选定的叠片的单独的冲模图案，在计算机控制的模压机上自动生产。 较轻的叠片可用于平衡曲柄，而不需要额外的平衡重量添加到电机外部。

Abstract: A laminated article in particular for electrical use including mutually superposed metal laminations provided with elements or clips for connecting the laminations together. The clips project from a surface of the laminations and are formed by deforming the laminations. The laminations include cavities angularly spaced apart from the clips. Each cavity is arranged to receive a respective clip from an adjacent lamination such that the laminations are coupled together via the clips and cavities. The cavities and clips constitute separate coupling elements of male-female type. The cavities are preferably through cavities extending from one planar surface of the lamination to an opposed planar surface.

Abstract: A rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.

Abstract: Elongated thin strip stock is blanked to form interlocking laminas for electric motor or generator rotors or stators at successive blanking stations. At a final assembly station the laminas are stacked and pressed into interlocking relationship. In response to an operator input a predetermined number of reversals, or half turns about the stack axis of the previously stacked lamina are provided in order to compensate for nonuniform strip thickness to obtain a rotor or stator of substantially uniform height. Alternatively the thickness of the strip stock is gauged at transversely spaced points on the strip to determine cross feed thickness variation in the strip whereupon the stacked laminas are automatically provided with a number of reversals about the stack axis in response to a thickness differential that would result in a parallelism error in the stack that exceeds a predetermined amount. Rotor conductor slots are formed in the stacked laminas and are skewed to the stack axis by providing arcuate indexing of each lamina relative to the next preceding lamina in the stack by an arcuate increment that is automatically determined in response to operator entered inputs relative to the stack height, the skew angle, nominal lamina thickness and skew direction.

Abstract: Motor for commercial and industrial applications such as golf carts and lift trucks. Features include a thin shell; stator; stator winding; and rotor. Rotor laminations have equally circumferentially spaced semi-closed slots having area for receiving conductors, and the ratio of the number of rotor lamination slots to the rotor outer diameter (measured in inches) is greater than 14.0. In one construction, this ratio is about 15.75; the ratio of the outer diameter to the rotor slot length is from about 9.04 to about 9.16; and the ratio of rotor slot depth or length to rotor slot opening width is from about 10.8 to about 12.5. Cylindrical stator lamination has a given outer diameter and a certain bore diameter determined by the distance between opposing poles. Through-bolt holes are located in the yoke, proximate the outer periphery thereof, and centered with respect to each pole. The ratio of stator pole neck minimum width to two times the yoke thickness or width is from about 0.809 to about 1.009. Methods of assembling motor components are also revealed.
