伺服电机和步进电机相比，有何优势？

<p>1.实现了位置，速度和力矩的闭环控制；克服了步进电机失步的问题；</p><p>2.高速性能好，一般额定转速能达到2000～6000转；&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</p><p>3.抗过载能力强，能承受三倍于额定转矩的负载，对有瞬间负载波动和要求快速起动的场合特别适用；</p><p>4.低速运行平稳，低速运行时不会产生类似于步进电机的步进运行现象。适用于有高速响应要求的场合；</p><p>5.电机加减速的动态相应时间短，一般在几十毫秒之内；</p><p>6.发热和噪音明显降低。</p><p><br/></p>
