Re: 油压驱动马达问题---[请教]

不明白你的意思，油压驱动马达是什末概念？是电机带油泵吗？。。。。最好能把示意图传上来。

Re: 油压驱动马达问题---[请教]

情况不是很清楚：
1.一般三相异步电机电压 380V   星接，三角接，11KW都不应该有38A的电流。
   按一般经验额定电流应在22A左右。空载应在十几A。（不清楚什么是220V ）
您讲的的启动一会后即停，应该是热继电器动作保护了。

查一下电机的线包电阻是否正确和平横。再量一下外部电压是否正确，和电机是否匹配。用手动转一下电机主轴是否灵活，没有卡死的现象。还有就是电机的轴承是否旷动过大。

Re: 油压驱动马达问题---[请教]

现在你在哪里呀，当地的相电压多少？电机的额定电压多少？是不是配呀？

Re: 油压驱动马达问题---[请教]

改一下电机的接法，当地220V的线电压，改成三角接法试试。
