can I run a CD rom motor with three phase line ac supply, 220 v/phase, step down to 9 volt by using three single phase transformers with wyne configuration, ... actually I tried and the cd-rom motor (9 pole) ran but with slower speed (I think)) and the stator got hot ... Also it is said in a post that cd rom motors are optimized for trapezoidal waveform rather the sinusoidal (i.e. mainline wave-form)... Can I get precise RPM i.e. 2250/mt from 9-pole cd-rom motor by 50 cycles/sec, three phase (step down) ac supply ...
