Problems solved by technology

This can cause thermal variations in motor operation, local overloading of welded joints causing electrical discontinuities such as short circuits in windings, for example due to weldments with minimal surface or cross-sectional area or with a small heat-affected zone, or due to solder spatter between pairs of wire ends

Embodiment Construction

[0020] Referring to the drawings, wherein like reference numerals represent like parts throughout the several views, Figure 1-6 Components shown in are not drawn to scale. Accordingly, the specific dimensions and applications provided in the drawings provided herein should not be considered limiting. A method and system are provided for connecting wire ends of a stator assembly. The method and system includes placing a crimpable element over a pair of wire ends of a stator assembly and extruding or deforming the crimpable element using a crimping tool to form a crimped joint. The crimped connector may be configured to provide an electrical connection between the wire ends of the wire end pair, for example by providing an electrically conductive contact area between the wire end portions of the wire end pair. figure 1 The stator assembly 10, also referred to as the stator, is shown prior to connecting the wire ends 28 by crimping. The stator 10 is generally configured as an...

Abstract

Provides a method and system, by placing the coilable element on the end of the wire to connect the end of the conductor to the end of the conductor, so that the wire end of the wire end pair is surrounded by a coilable element, and the use of a rolling tool so that the coilable element deformation to form a warped joint. The crimped connector is configured to provide an electrical connection between the wire ends of the wire end pair. Wire ends can be physically in contact with each other by means of rollable elements. The conductor end portion of the stator may be immersed in a melted welding bath to form a brazing head that will include a wire end pair of the coiled joint connected together. The stator can be configured as a rod pin stator, which includes a plurality of rod pins that limit the end of the wire.

Description

technical field [0001] The present invention relates to methods and systems for stator wires of electrical devices. Background technique [0002] Electrical devices such as electric motors and generators having fixed motor / generator housings are known. A shaft-mounted rotor is positioned coaxially within the stator and is rotatable relative to the stator about the longitudinal axis of the shaft to transmit the force capacity of the electric motor. Current flowing through the stator creates a magnetic field that tends to rotate the rotor and shaft. [0003] Some stators are usually configured as annular rings and are formed by stacking sheets or laminations of highly magnetic steel. A specific pattern of copper windings is typically placed in slots in the laminate stack through which current flows to magnetize portions of the stator assembly and create a reaction force that causes the rotor to rotate. [0004] A barpin stator is a special type of stator that includes a win...
