FIELD: engines and pumps.
SUBSTANCE: invention relates to windmill generator (1) with closed internal cooling circuit with stator (4) made of metal sheet. Said stator has the system of windings with front parts (10) composed thereby. Note here that stator (4) is surrounded in at least the sheet stack area by cooling shell (3). Note also that permanent magnets (18) of rotor (5) are arranged on shell (6) of salient-pole rotor shaped to hollow shaft. Note here that salient-pole rotor shell (6) is connected via bearing elements (28) on end sides with shaft (7) or shaft ends and locked thereat. Note here that said hollow shaft accommodates at least one pipe (29, 33) with its side surface located equidistantly from salient-pole rotor shell (6). Note also that fans (24, 25) are arranged at rotor end sides. Said pipe is fitted inside hollow shaft to make cooling channels.
EFFECT: sufficient cooling.
