Dual Stator Permanent Magnet Direct-drive Wind Power Generator with Stationary Shaft Support

摘要

A double-stator permanent magnetic direct-driven wind power generator supported by a fixed shaft (17) includes a wheel hub (1), the fixed shaft, a front bearing (15), shaft sleeves (16), a back bearing (18), a front bearing end cover (2), back bearing positioning elements (19), hollow rotating shafts (3), a rotor disk (5), a rotor (8), an outer stator (7), an inner stator (9), an inner stator bracket (11), a generator front end cover (4), a generator shell (6) and a frame (14). The fixed shaft is connected with the frame; the front bearing and the back bearing are mounted on the fixed shaft; the shaft sleeves are sleeved on the fixed shaft and arranged between inner rings of the front bearing and the back bearing; the back bearing locating elements are arranged outside the back bearing; the hollow rotating shafts are sleeved on the front and back bearings of the fixed shaft; the front bearing end cover is connected with the hollow rotating shafts. The generator reduces weight and cost greatly.
