Abstract:
A dynamo-electric machine, comprising:a. a field member having north and south magnetic pole portions to create a flux field extending between said magnetic pole portions;b. an armature assembly rotatably mounted in said machine to rotate through said flux field, said armature assembly comprising:i. a core positioned in said flux field;ii. coil means comprising a plurality of induction coils positioned adjacent to said core and positioned to move through said flux field during rotation of said armature assembly;iii. switch means mounted to said armature assembly so as to be rotatable therewith, said switch means being operatively connected to said coil means, in a manner that current can be caused to flow selectively through said coil means in a manner to cause a desired interaction of said coil means in said flux field;c. mechanical power transfer means connected to said armature assembly so as to be rotatable therewith in power transmitting relationship;d. electrical power transfer means for transferring power between said armature assembly and stationary terminals on said field member;e. said switch means being connected with said electrical power transfer means and said coil means so that current between said electrical power transfer means and said coil means is selectively controlled by said switch means; andf. control means responsive to sensed analog characteristics of said flux field to operate said switch means to control direction and timing of current in said coils;whereby current flow in said coils can be optimized to accomplish desired power transfer between the electrical power transfer means and the mechanical power transfer means.
