Embodiment Construction

[0014] The invention and further advantageous embodiments of the invention will be described in detail below with the aid of an exemplary embodiment shown in the drawings.

[0015] figure 1 It is a longitudinal sectional view of the wind power generator 1 including end A and end B, wherein end A faces the wind turbine of the wind power equipment which is not shown in detail in the figure. The mechanical coupling to the wind turbine is established directly via a shaft or at least one journal 7 or indirectly via a gear mechanism. The wind turbine 1 is accommodated in a housing 2 which has inlets and outlets 14 , 15 for supplying and discharging coolant to a cooling jacket 3 which is arranged between the housing 2 and the stator 4 . Losses are removed from the laminated core of the stator 4 via the cooling jacket 3 and the cooling medium flowing in the cooling channels 17 .

[0016] The end faces of the laminated cores of the stator 4 form the winding heads 10, which protrude a...

Abstract

The invention relates to a wind power generator (1) having a closed inner coolant circuit, having a stator (4) implemented as sheet metal and comprising a winding system forming winding heads (10) at the end faces of the stator, wherein the stator (4) is enclosed by a cooling shell (3) at least in the area of the laminated core thereof, wherein permanent magnets (18) of a rotor (5) are disposed on a magnet wheel shell (6) implemented as a hollow shaft, wherein the magnet wheel shell (6) is rotationally fixed to a shaft or shaft stubs by means of support elements (28) at the end faces thereof, wherein the hollow shaft comprises at least one tube (29, 33)in the interior thereof, the shell surface thereof running equidistant from the magnet wheel shell (6), and wherein blowers (24, 25) are mounted on the end faces of the rotor (5).

Description

technical field [0001] The invention relates to a wind power generator with an internal cooling circuit. The generator comprises a stator composed of metal laminations. The stator has a winding system which forms a winding head at the end face of the stator, wherein a cooling jacket contains at least In the region of the laminated core of the stator, the permanent magnets of a rotor are arranged on a magnetic wheel sleeve which is part of the hollow shaft. Background technique [0002] Wind turbines, like other generators, require cooling of their functional components. In this case, especially the interior of the wind turbine (i.e. the electrical area) is at risk from impurities or aggressive media which, for example, attack the insulation or adversely affect the electrical breakdown strength . This can adversely affect the operation of the wind turbine or cause it to malfunction. It is therefore common practice in this field to equip generators with a closed internal co...
