这个是开环启动时的PWM波形。启动时电机像被卡住一样，并且有震动现象存在，请问是什么原因。

(function(id)
{
var v = document.getElementById(id), isSafari = navigator.userAgent.indexOf(‘Safari’) != -1 && navigator.userAgent.indexOf(‘Chrome’) == -1;var op = v.style.position, ol = v.style.left, or = v.style.right, fe = [];
var nodeLimit = 50;
checkVideo = function() {
if (!v.canPlayType || v.error) {
var bound = 0;
while (v.childNodes.length > 0 && bound 0 && bound < nodeLimit) {
bound++;
if (v.childNodes[0].nodeName != 'SOURCE') {
fe[fe.length] = v.childNodes[0];
v.parentNode.insertBefore(v.childNodes[0], v);
}
}
window.setTimeout(checkVideoRendered, 249);
} else if (v.readyState == 0) {
window.setTimeout(checkVideo, 249);
}
},
checkVideoRendered = function() {
if (v.networkState == 1 && v.readyState == 4) {
v.style.position = op;
v.style.left = ol;
v.style.right = or;

你参考这个例程去试试开环启动。

(function(id)
{
var v = document.getElementById(id), isSafari = navigator.userAgent.indexOf(‘Safari’) != -1 && navigator.userAgent.indexOf(‘Chrome’) == -1;var op = v.style.position, ol = v.style.left, or = v.style.right, fe = [];
var nodeLimit = 50;
checkVideo = function() {
if (!v.canPlayType || v.error) {
var bound = 0;
while (v.childNodes.length > 0 && bound 0 && bound < nodeLimit) {
bound++;
if (v.childNodes[0].nodeName != 'SOURCE') {
fe[fe.length] = v.childNodes[0];
v.parentNode.insertBefore(v.childNodes[0], v);
}
}
window.setTimeout(checkVideoRendered, 249);
} else if (v.readyState == 0) {
window.setTimeout(checkVideo, 249);
}
},
checkVideoRendered = function() {
if (v.networkState == 1 && v.readyState == 4) {
v.style.position = op;
v.style.left = ol;
v.style.right = or;
for (var i = 0; i < fe.length; i++) {
fe[i].parentNode.removeChild(fe[i]);
}
} else {
window.setTimeout(checkVideoRendered, 249);
}
}
if (navigator.userAgent.indexOf('iPad') == -1 && navigator.userAgent.indexOf('iPhone') == -1 && navigator.userAgent.indexOf('iPod') == -1) {
window.setTimeout(checkVideo, 249);
}
})('v_769f6fc4da694db7849923e7e83855e2');

user5805327：controlsuite中有PMSM的控制例程，哪个芯片我忘了，反正也是C2000的，楼主可以去看看
