日本三菱电机公司为适应发动机轻量化、和小型化的要求、研制成了世界上最小的高性能发动机起动机,其功率为1.2kw,直径70mm、长205mm、重量为3.1kg。它比目前最小的起动机还要轻30～50％。小型化的主要原因是把传统的外部减速改为内部减速(行星齿轮式),由于同轴的缘故,可大大的减小体积。另外,为了达 Japan’s Mitsubishi Electric Corporation to adapt to the engine lightweight, and miniaturization requirements, developed the world’s smallest high-performance engine starter, the power of 1.2kw, diameter 70mm, length 205mm, weight of 3.1kg. It is 30 to 50% lighter than the smallest starter currently available. The main reason for miniaturization is to change the conventional external deceleration to internal deceleration (planetary gear type), which can greatly reduce the size due to the coaxiality. In addition, in order to reach
