Question: was that a single-phase motor or a three-phase motor? Many
commercial units have the advantage of 3-phase power, which allows a
much more efficient motor design. It is generally impossible to get
3-phase power in a residential structure unless you install your own
converter (formerly a rotary unit, although I understand solid state
systems are now available) which wastes a lot of electricity.
