动自行车驱动用</SPAN>SR</SPAN>电机的设计指标</SPAN> </SPAN>
好杰电动车</SPAN></SPAN></SPAN>我们通过对电动自行车市场的调研并且基于研究开发</SPAN>SRD</SPAN>的经验，提出如下</SPAN>SR</SPAN>电机的设计指标：</SPAN>
(1)</SPAN>额定电压：</SPAN>36V(DC)</SPAN>；</SPAN>
(2)</SPAN>额定电流</SPAN> 6A</SPAN>；</SPAN>
(3)</SPAN>额定功率</SPAN>150W</SPAN>；</SPAN>
(4)</SPAN>额定转速</SPAN>190</SPAN>转</SPAN>/</SPAN>分；在</SPAN>0</SPAN>转</SPAN>/</SPAN>分至</SPAN>210</SPAN>转</SPAN>/</SPAN>分范围内无级调速；</SPAN>
(5)</SPAN>额定效率</SPAN>>75%</SPAN>；</SPAN>
(6)</SPAN>额定转矩</SPAN>>5.8Nm,</SPAN>过载倍数</SPAN>>2.5</SPAN>；</SPAN>
(7)</SPAN>噪音</SPAN>；</SPAN>
(8)</SPAN>外型为圆盘型，直径</SPAN>×</SPAN>轴向尺寸控制在</SPAN>180mm</SPAN>×40mm</SPAN>之内；</SPAN>
(9)</SPAN>载重</SPAN>90</SPAN>公斤。</SPAN>
采用电压</SPAN>PWM</SPAN>控制实现</SPAN>SR</SPAN>电机无级调速，控制器具有如下基本功能：</SPAN>
(1)</SPAN>电池容量显示；</SPAN>
(2)</SPAN>级调速；</SPAN>
(3)</SPAN>起动电流缓冲；</SPAN>
(4)</SPAN>过载限流及保护；</SPAN>
(5)</SPAN>欠压保护；</SPAN>
(6)</SPAN>刹车制动。</SPAN>
设计推荐选用</SPAN>36</SPAN>伏</SPAN>7</SPAN>安时的铅酸免维护电池。</SPAN>好杰电动车</SPAN></SPAN></SPAN>
