The invention relates to a method and device for producing an electric machine, an electric machine with a commutator, having commutator hooks for fixing electric wire windings with solder arranged between the commutator hooks and the wire winding and two electrodes arranged adjacent to each other which are pressed against the commutator hooks. An electric current is passed through the commutator hooks by means of electrodes such that the solder melts and forms a connection to the wire winding.

The invention relates to an insulating mask arrangement for electrically insulating an electric winding from an iron core (13) of an electrical machine (20), at least one mask element (11, 12) being arranged on the iron core (13). The invention provides that the iron core (13), in its axial extension (15), is covered throughout in its winding-guiding grooves (24) by one or more mask elements (11, 12). The invention also relates to an armature and to an electrical machine.
摘要:
A method for sheathing an armature for electric machines, in which a stack of lamellae that is equipped with grooves for armature windings is mounted on an armature shaft by means of a bore and is provided with at least one groove insulation with the aid of the sheathing process. The sheathing plastic flows through ducts that extend along the bore of the stack and the armature shaft. The plastic is molded in only on a first face of the stack and flows into the grooves and through the ducts. The plastic invades the grooves also from the second face after being discharged from the ducts and converges with the plastic discharged from the first face. The method implements fixing and insulation of the grooves while the groove insulation is provided with a minimum layer thickness for such sheathings at the bottom thereof in order to allow for maximum copper fillings.

The invention relates to a commutator with contact segments, arranged at a distance from each other and forming a brush running surface. Each contact segment is soldered to a securing portion of a metal segment support piece. The commutator has a hub body made from an electrically insulating material which supports the segment support pieces which are each provided with a winding connector hook. According to the invention, at least one solder barrier recess is provided in the upper side of the securing portion facing the contact segment and/or in the under side of the contact segment facing the securing portion.

A device for the metering of fluidizable bulk materials, having a storage tank and a mass-flow-measuring device for the material and a fluidizing device, which is connected to the storage tank via an aperture of adjustable size, and a control valve for controlling the supply of compressed air to the fluidizing device, wherein a pressure gauge is provided downstream of the fluidizing device, in the direction of flow, and the pressure gauge and control valve are connected via a first control circuit, and the supply of compressed air to the fluidizing device is metered by this control circuit in such a manner that a constant, in each case preselectable subatmospheric pressure prevails in the fluidizing device, and the mass-flow-measuring device and the aperture of adjustable size are connected via a second control circuit, and the size of the adjustable aperture is set by this control circuit in such a manner that a defined quantity of bulk material enters the fluidizing device.
摘要:
A system for determining a signal running time between a position measuring system and an evaluation unit. The system includes a position measuring system that has a graduation connected to a moving element, a scanning unit that scans the graduation, wherein scanning of the graduation generates signals representative of a position of the moving element and a transceiver means for generating serial data that is transmitted along a data line connected to the transceiver. The system further includes an evaluation unit connected to the data line, the evaluation unit having means for determining a signal running time between the position measuring system and the evaluation unit.

A collapsible hard top for convertible motor vehicle and including a rigid top panel displaceable between a closed position in which it overlaps an entire passenger compartment of the vehicle, and an open rearward position, and a rear window a position of which is independent of a position of the hard top and which pivots between an upright position, in which the rear window extends upward of motor vehicle body contour, and lowered position in which the rear window projects in to the passenger compartment, with a distance between a back side of rear posts of the top panel and a B-pillar of the vehicle body corresponding at least to a height of the hard top.
摘要:
A cutter-infeed apparatus for cutting installations for articles in tape or strip form or film-like articles, circular cutters being fastened on upper and lower shafts and displaced with respect to one another for fixing the cutter infeed, and an electrical insulation between the upper and lower shafts making it possible to detect the cutter contact during infeeding and thereby make the infeeding operation automatable. It is also possible to make the infeeding of the individual cutters or cutter-box cutters such that it can be set depending on the difference in speed of the upper and lower shafts. The apparatus can be used for cutting machines of all types in which thin, uncoated or coated polymer films or metal foils can be cut.
