more powerful

what does "more powerful" mean in this context? higher efficiency? or higher max torque?

    More torque per weight of motor, or more power generated per torque applied to it.

    i see so just more lightweight motors/generators then.

    which makes sense considering that magnets are the functional part of the device and everything else is just there to provide mechanical stability.
