Abstract
Official abstract text for this publication.
A high-efficiency, high specific power electric motor/generator for aircraft use provides a cantilevered external rotor removed from load thrust and vibration by an isolator and hearing set between the rotor and stator reducing material demands and weight otherwise required for stiffness to preserve close rotor/stator proximity.
First claim
Opening claim text (preview).
What we claim is: 1. An electric machine comprising: a frame; a stator providing a stator body having a circumferential periphery supporting a series of electrically independent coils facing outward and spaced therealong; a rotor providing a rotatable shaft passing through the stator to a first end that is attached to an endplate extending radially from the shaft to a periphery having a diameter outside of the stator and joining an end of a permanent magnet form coaxially surr…
