I'm thinking of building a turntable power supply based on readily available AD9833 breakout modules. The AD9833 is a DDS waveform synthesiser that is easy to control with a microcontroller such as the Arduino. I was planning to use 2 of them, 1 per phase.
The motor to be driven will be either the 12V or 24V Premotec 9904 series ac synchronous motor as used in countless belt drive decks. The AD9833 modules output about 600MV peak to peak. Is n ordinary chip amp the optimal solution to boost the output to drive the motor or is there a better way? If I went with an amplifier, can somebody advise how I would calculate the power requirements to work out the optimal solution where price, performance and power are all considerations?
I have looked at other projects including the Sincos and Meldano but I want to build something that better suits my requirements than either. Software is however my forte, not hardware. Any advice, and links to other designs greatly appreciated.
