Can someone please help me with this issue:
I have just built two golden motor blt-800 into a cargo bike. I use the Golden motor "cruise" controllers.
When the motors get some load they start behave strange: it seems like they periodically stops for a millisecond. I am 95% sure that it is not a mechanical issue.
I tried to make a video, se https://drive.google.com/open?id=1waLPS67R9aCt6SVczi0mk_Y9PtaGKdcA. In the video I hold the brake handle to make a load to the motor, and I let the motor spin relatively slowly so you might see that the wheel stops up periodically. It happens the both motors. It makes a loud bang-noise. One reason is that the cargo bike has a aluminium box which amplifies the sound:-/ (so this issue might not be so obvious when these motors are used in a normal bicycle frame...)
The controllers are restored to fabric settings (30A continous, 120deg phase angle, see attched screenshot). Battery voltage is around 50V
What can the reason be?? Is it just a crappy motor and controller?
