Definitions
- the present invention relates to the field of electric machines. It relates to a rotary electric machine according to the preamble of claim 1.
- Double-fed asynchronous machines are well known. They have a structure that can be exemplified as follows.
- the rotating electrical machine or asynchronous machine comprises a rotatable about an axis rotor which is concentrically surrounded by a stator.
- the stator has a stator winding, which is accommodated in a laminated stator core and protrudes from the stator laminated body at the ends in the form of a stator winding head.
- the rotor comprises a central body with a shaft, at the end of which slip rings for current transmission are arranged. Around the central body extends a rotor body which carries a rotor winding which emerges from the rotor body at the ends in the form of a rotor winding head. The rotor winding must be secured against the occurring centrifugal forces.
- Rotor laminated core of the rotor plate body serves to absorb these forces and at the same time defines the path of the magnetic flux.
- a Hilfsrim 24 is arranged at the ends of the rotor body.
- the Hilfsrim as well as the rotor laminated body consist of layered sheets, which are pressed in the axial direction to a composite. The pressing takes place by means of a plurality of bolts extending in the axial direction through the
- Rotor sheet body or Rim is provided for distributing the pressure of a press plate.
- the rotor body and the central body of the rotor are independent components that must be engaged to transmit torques. It is known from the document US Pat. No. 4,942,324 (see FIG. 1 there) to provide wedges (26) for coupling between the rim (24) and the hub (9) which engage corresponding cut grooves on the inner circumference of the rim (24) , This known type of connection is shown in the single figure of the present application in the right half for the sheet segment 27 ', where the grooves 29' are arranged for engagement between the rim and the central body on the inner circumference of the sheet metal segment 27 '.
- the radial height of the cams is equal to the groove depth of the grooves.
- Sheet metal segments formed As a preferred method, punching or shaping by means of laser are to be mentioned here in particular.
- Sheet metal segments of the rotor core stack offset from each other.
- FIGURE shows a sheet segment for the rotor body of a sheet metal
- Asynchronous machine with positive connection means according to an embodiment of the invention.
- Embodiment for the solution according to the invention (left half of the figure).
- the grooves 29 can move more inward to the center of the rotor 1 1, as can be seen from the left half of the figure.
- This measure according to the invention makes it possible to enlarge the yoke, because the holes or holes 28 can be offset for the shear pin also inward, without the inner or outer radius of the sheet respectively. Change rotor. In this way, the power transmission from
- the grooves 29 may have a rectangular, approximately rectangular, a trapezoidal or any other cross-sectional shape in a conventional manner.
- the sheet segments 27 are blanked. That is, from sheet to sheet the sheet segments 27 are offset from each other. This measure serves to increase the mechanical integrity of the
