Hi
I need a help. I do have a DC TachoGenerator whereby i can measure the DC voltage if the shaft rotates.
The problem is:
When I rotate the shaft at CW, I got a fixed plus voltage.But when i rotate to CCW, the voltage is minus but slowly later it decrease to zero. (even the shaft still rotating)
Why?
