Power Supply Suggestions please..

i will be running other things requiring voltages less than 50v so this should cover the lot.

Then you should use the right size (750VA for 5 motors) transformer for the motors and get transformer(s) with lower voltage windings to power the lower voltage appliances, otherwise you've got to somehow drop the voltage further which is complicated to with any efficiency.

ok I decided on going for this one: Standard Range Toroidal Transformers: CM1200171: 1200VA 230v to 120v

Er, I hope not as that has a 120V secondary not 50V or 25+25V which is what you need for the motors.

its not as big as the other one but then i Bought two!!

So you'll have about 1.65kW surplus after powering the stepper motors - must be planning some pretty serious optional extras to use that much. Perhaps the machine is going to make tea...
