Dynamic balance de-weight structure of internal combustion engine generator rotor

The invention relates to a dynamic balance de-weight structure of an internal combustion engine generator rotor. The structure comprises a rotor, and the junction of the outer circle and the outer end surface of a rotor magnetic pole is a right angle; the outer circle of the rotor comprises a rotor outer circle magnetic circuit working surface and rotor outer circle magnetic circuit non-working surfaces positioned in two side areas outside the rotor outer circle magnetic circuit working surface; a de-weight part is arranged on the rotor outer circle magnetic circuit non-working surfaces so that the product performance is not influenced; the de-weight part is arranged on the outer circle of the generator rotor so that the de-weight efficiency is high; and interference between a de-weight cutter and the fan is avoided, and equipment automation is easy to achieve. 本发明涉及一种内燃机发电机转子的动平衡去重结构，包括转子，所述转子磁极的外圆与外端面交接处为直角；所述转子的外圆包括转子外圆磁路工作面、及位于所述转子外圆磁路工作面之外两边区域的转子外圆磁路非工作面；去重部位设置在所述转子外圆磁路非工作面，不影响产品性能；本发明的去重部位在发电机转子外圆，去重效率高
