Toroids have a lot of advantages for steppers which don't require regulated power. Cost is a big one at higher voltages. Something like this might suit you (without knowing your motor specs.)

With some drivers, like the Lams I am using now, they accept AC voltage so it eliminates the need for the regulator stage so that reduces the failure points. In fact, Lam have a 110V driver so in the US, no toroid would be required.

When I upgraded my machine I used two 32 volt off the shelf transformers to give 64 volts AC @ 20 amps. See pic. There is a bank of 8 fuses there as per the Lam recommendations and they go straight to the drives.

AC converts to DC at a factor of around 1.4 so the motors get about 90 volts.

Re servos, it takes a bit to get your head around a servo torque curve after using steppers. A said you get constant torque right through to about 3000 rpm or so then it falls to nothing. So the guys are probably right when they say reductions are not required. This does make designing with servos much easier. We found with steppers, pinion diameter, pinion reduction ratio and motor inertia were the key design parameters. Inductance not so much but the ratio between resistance and inductance had some impact.
