What do I need to convert a fixed frequency digital output to a fixed Vmax sine wave?
My plan is to set the frequency between 1 & 100 Hz and drive a step up transformer to give 240 volts at any frequency I choose.
This will be used to drive a small synchronous motor such as a Fiber M51r.
The Power required is very low & I realise that I may have to compromise the range if necessary.
(I still haven’t worked out how to use the PWM feature)
