Hi everybody,
Trying to replace an old brushed motor with a brusheless one in an old tape recorder. Naturally it requires a controller so I wonder if this could be built on microcontroller board and how complicated would it be. Here is what I have to deal with:
- 24v input power
- about 10W-13W brushless motor with hall sensor
- 2 distinct rotation speeds
- 2 rotation directions
- RPM pitch control with an encoder (±20%)
Being a tape recorder, the rpm accuracy and consistency is of absolute importance, that's why the most important question is "how accuratly a microcontroller can manage the rotation speed?" I met many cases where the rotation adjustments happen too slow resulting in rythmically floating of the sound.
I am a hobbyist, some skills in electronics but almost no knowledge in microcontrollers. So any hint or advise would be great to start with: like what kind of board would fit, are there suitable libraries o codes I could use? etc...
Thanks in advance
