Embodiment Construction

[0041] Figure 2a with Figure 2b Shown is a stator 11 with axis X having a core 12 consisting of teeth 14 regularly distributed on the inner periphery and slots 15 open towards the inside, two consecutive slots 15 divided by teeth 14 separated. These teeth 14 also have two parallel edges, webs of material corresponding to the yoke 17 present between the bottom of the groove 15 and the outer periphery of the core 12 . The core 12 is formed by a stack of steel laminations made of ferromagnetic material, extending in a radial plane perpendicular to the axis X. The stack of steel laminations is held by rivets (not shown) which pass axially completely through the stack of steel laminations.

[0042] The stator is part of a polyphase rotating electrical machine comprising a stator winding fitted with a number of coils 19 pre-assembled here and a neutral point which is referred to as the neutral point of the motor, for example from document EP0831580 figure 1 as shown. The coil...

Abstract

The invention relates to an interconnector (22) for a stator of an electric machine. This interconnector (22) includes at least four frames (31-34) of annular shape, these frames (31-34) being stacked axially on each other and insulated from each other, each frame (31-34) is supported on its periphery internal lugs (36) protruding inwardly towards the frame (31-34) for welding the ends of stator coils. One of the frames (31) is named as a neutral frame and is intended to be connected to the neutral point of the electric machine, the other three frames (32-34) are named as phase frames, each phase frame is intended to be connected to a phase of the electric machine. The invention also relates to a stator having a winding formed by the coils having ends connected to the interconnector (22) according to the invention.

Description

technical field [0001] The present invention relates to a connector for a motor stator and related motor stators. [0002] The invention relates to the field of electrical machines, such as motors, alternators or alterno-starters. [0003] The invention has a particularly advantageous application with respect to alternators, which are used in so-called "range extender" systems aimed at increasing the autonomy of electric vehicles. For this purpose, these systems include low power The internal combustion engine, which mechanically rotates the alternator, is intended to generate electrical energy for supplying the battery of the vehicle's electric traction motor when necessary. Background technique [0004] It is known that electric machines comprise a stator and a rotor integral with a shaft. The rotor may be integral with the drive or driven shaft and may be part of a rotating electric machine in the form of an alternator as described in document EP0803962, or in the form ...
