Analog Robotics Motors

What if you customize transformers to step up set voltage values and then have separate arm of the transformer for stepping up the current ? We would then need to splice the stepped up voltage and current for a singular higher power amplification ratio. We can also use the transformer to drive motors. If we use the same transformer to step-up the power and various frequencies,each frequency would drive a different motor and use attenuated analog logic circuits (band-pass/band-stop) to filter the amplified signals. This would work ideally with AM radios because the signal would determine the speed and power behind the motor as well as the duration . This would make for some interesting analog robotic applications !
