Dynamo-electric machines and control and operating system for the same

Abstract

The dynamo-electric machine comprising a field member creating a flux field extending between magnetic pole portions. There is an armature assembly rotated in the machine comprising a core and a plurality of induction coils. There are switches mounted in the armature assembly so as to be rotatable therewith, and the switches are arranged to cause the current to flow selectively through the coils. By properly controlling the switches to control direction and timing of the current, the current flow in the coils can be optimized to accomplish desired power transfer.

Therefore I claim:  
     
         1 . 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 the 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 transfer means connected to said armature assembly so as to be rotatable therewith in power transmitting relationship;    d) electrical power transfer means having an operative power connection with said switch means;    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;    f) control means 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.
