Hello everybody,

The Leadshine MA860 driver contains a bridge rectifier and I think 2 capacitors with a relatively small capacitance inside it,
I think that the DC current is not smoothing enough when powering it with AC transformer. (sorry if I am wrong!)

- Is it normal? or it causes more heating and vibration to the motors?
- How to size the transformer and how the back EMF energy is absorbed since we have not big capacitors?

Thanks for your help!
