The lack of torque multiplication by removing a variator/gearbox can be
partially solved by just using a bigger motor.  Its my understanding that
Monarch use a 10hp motor+VFD for 10EE retrofits instead of using a
gearbox.  Simple.  The original MG set versions used a 3hp??  Though I have
no idea w/ all the series conversion efficiencies n that thing what you
realistically got out of the last shaft at the end.  You can get another
~2x multiplier by overspeeding an 1800rpm motor to 3600.
