For the sake of simple centrifugal force-proof fixation of the exciter winding, it is provided that the exciter winding (24) is disposed on a winding carrier (11), which has means (32, 33) for firmly clamping the winding ends (26, 28) (FIG. 2).

Abstract: The press (2) comprises a housing (4) in the forward part of which a slide ram (22) is mounted on bearings (62). The ram (22) is driven by an electric motor (26) by way of reduction gear box (24), having an output shaft (79) to which is eccentrically mounted a stub shaft (78) surrounded by a roller bearing ring (80) in a bearing block roller (82). As the output shaft (79) is rotated by the motor (26), the roller (82) rolls back and forth along a guideway (74) formed in the rear face of the ram (22), to take up the eccentricity of the shaft (78). The ram (22) is centrally mounted in its bearings (62) to avoid its canting as it is driven.

The control circuit arrangement (89) also comprises a computer (108) having registered therein a desired motor speed program (112), and a motor control circuit (104) for comparing the outputs of the encoder (30) and the sensors (94) with the program (112) and feeding the result of the comparison to a motor drive pulse generator (96) to control the speed of the motor (26) in accordance with the program (112) and to stop motor (26) upon the press ram (22) reaching a position at least proximate to its home position (0.degree.) at the end of a cycle thereof.

Abstract: The installation comprises a press (2) having a press ram (22) which is driven by a drive electric motor (26), to drive an applicator ram (47) of an electrical terminal applicator (44). A control circuit arrangement (89) controls the drive motor (26) so that the press ram (22) is brought at least substantially to its top-dead-center, home position after each press cycle and also has sensors (140 and 142) for sensing the absence of a terminal (T) from a strip (S) and of terminals (T) fed to the applicator (44), to cause the press ram (22) to carry out an extra cycle to place the next following terminal (T) on the anvil (58) of the applicator (44). The control circuit arrangement (89) controls a lead making machine (114) which includes the applicator (44); and performs various other control functions.

Abstract: A press ram (6) is coupled to an applicator ram (20) to drive it, by means of a claw (54) which engages beneath an adaptor head (34) on the applicator ram (20). The claw (54) is formed on a slide (46) which is vertically shiftable in a guideway (42) in the press ram (6), the position of the slide (46) in its guideway (42) being adjustable by means of adjustment screw (62) from which projects eccentrically, a spigot (66) which engages in a slot (50) in the slide (46). The adjustment screw (62) can be rotated by means of a tool blade (B) to raise the slide (46) to take up slack between the press ram (6) and the applicator ram (20). A set screw (74) is provided for securing the slide (46) in its position of adjustment.

Abstract: The commutating poles of vehicular-type dc motors, for example for trolley buses or trolley cars, are made by winding, on edge, a copper strip, permitting the wound copper strip to resiliently, spring-like expand so that the individual spiral loops thereof will be slightly spaced from each other, and then exposing the copper strip in a fluidized bed to an insulating powder, for example polyethylene or polyurethane, which is subsequently cured in a hardening or sintering process.

Abstract: The stator of a three phase AC generator is wound automatically. A first set of partial windings consitutes the first winding. Each of the partial windings has at least one turn. The first partial winding is wound in slots 1 and 4 in the clockwise direction, the second in slots 7 and 4 in the counterclockwise direction, etc. Before the second partial winding of the first set is wound, the first partial windings of the second and third phase are wound in slots 2 and 5 and 3 and 6, respectively. Similarly, after the counterclockwise winding in slots 4 and 7, the second partial windings of the second and third phase are wound in the counterclockwise direction in slots 8 and 5 and 9 and 6, respectively. This procedure is repeated until all slots are filled.

Abstract: The first, second and third winding for the stator of a three phase AC machine having n grooves per pole and phase are wound either sequentially or simultaneously. When wound sequentially, the first, second and third winding start at, respectively, a first, second and third groove and end at a first, second and third end groove. The starting grooves are adjacent grooves, that is spaced from each other by a number of grooves equal to n. The same is true for the end grooves. The wires are then interconnected such that the winding start and the winding end of the second winding are electrically interchanged. The winding process takes place in one direction only. When all windings are wound simultaneously, the winding process takes place in a first direction and, upon reaching the end grooves, the winding direction is reversed without creating a winding end at the end grooves. The winding ends are created when the winding in the opposite direction is completed.
