The DC brushless motor of the power-assisted bicycle was used as a 3-phase Permanent Magnet Synchronous Generator. The 3-phase PMSG is driven directly by the chain attached wheel sprocket.The rectified voltage from the 3-phase AC voltage is influenced considerably by the commutation reactance caused by the armature windings. In this research, the value of the commutation reactance can be obtained from the experimental results and regarding the influence of this reactance is investigated.The wattmeter equipped with the one-chip microcomputer was produced to measure and display the output electric power. The calculation accuracy of the produced wattmeter is conformed by YEW WT230 digital wattmeter. For the electric power measurement of this manpower generation system, it was confirmed that 100-millisecond sampling period is accurate enough for practical usage.This generation system obtained 128[W]x60[s]=7680[J] electrical energy. And the improvement of mechanical driving system enables output electric power to increase.The buck-type switching regulator is used to stabilize dc output voltage and the switching frequency will is decided to 50μs after consideration of processing capability of the microcomputer.

助力自行车的直流无刷电机用作三相永磁同步发电机。三相永磁同步发电机由链轮直接驱动。三相交流电压的整流电压很大程度上受到电枢绕组引起的换相电抗的影响。本研究通过实验结果求得换相电抗的值，并对该电抗的影响进行了研究。制作了配备单片机的功率表，用于测量和显示输出电功率。所生产的功率表的计算精度与YEW WT230数字功率表相符。对于该人力发电系统的电力测量，已证实100毫秒采样周期对于实际使用来说足够准确。该发电系统获得了128[W]x60[s]=7680[J]电能。机械驱动系统的改进使输出电功率增大。采用降压型开关调节器稳定直流输出电压，考虑微机的处理能力，开关频率定为50μs。
