Default Re: Using an electronic transformer for a model tram motor?

UF400X diodes are what you need.
I looked into model control some years ago and came to the conclusion that the current the motor takes can be used to control absolute speed and provide a speed indicator on the controller.
The motor produces a current waveform that can be measured.
