Hello.
It appears that we do not make any of the products you are using, so I do not have any specific suggestions about what is going on or what might fix it.
However, keep in mind that motors usually draw many times their free running current when starting, and that might be too quick for your meter to measure. So, you might consider looking at your setup with an oscilloscope to try to isolate the problem and understand what is going on better.
