The invention provides an external rotor generator for a range extender, which comprises a stator shell, a motor shell, a stator core, a flywheel rotor, an adapter shaft and a rotary transformer, and is characterized in that the adapter shaft is of a stepped convex structure and is provided with a first boss, a second boss and a third boss; a first boss of the adapter shaft penetrates out of the flywheel rotor and is fixed with an inner ring of the rotary transformer, an outer ring of the rotary transformer is fixedly connected with the motor shell, and the flywheel rotor is arranged on a second boss of the adapter shaft in a penetrating and sleeving mode and is fixed with a third boss through a bolt; the stator iron core is pressed on the annular bulge structure of the stator shell in the inner cavity of the flywheel rotor; the outer rotor generator for the range extender has the advantages of being short in length, light in weight, simple in overall structure, few in fault points and the like, the weight of the rotor can be lighter under the condition that rotational inertia is kept unchanged, and the influence of the weight of the rotor on an engine bearing bush is reduced.

    本发明提供一种增程器用外转子发电机,包括:定子壳体、电机壳体、定子铁芯、飞轮转子、转接轴和旋转变压器,所述转接轴为阶梯式凸起结构,其设有第一凸台、第二凸台和第三凸台;所述转接轴的第一凸台穿出飞轮转子与旋转变压器的内圈固定,所述旋转变压器的外圈与电机壳体固定连接,所述飞轮转子穿套在转接轴的第二凸台上并与第三凸台通过螺栓固定;所述定子铁芯在飞轮转子的内腔中压装在定子壳体的环形凸起结构上;本发明提供的增程器用外转子发电机,具有长度短、重量轻、整体结构简单、故障点少等优势,能够在保持转动惯量不变的情况下使转子重量更轻,降低转子重量对发动机轴瓦的影响。
