Title:
ELECTRODYNAMIC MACHINE UTILIZING SUPERPOLES
Document Type and Number:
WIPO Patent Application WO2001001546
Kind Code:
A3
Abstract:
An electrodynamic machine utilizing superpoles includes a relatively stationary coil assembly (24) carried on a support shaft (26) and a magnet array (28) that is designed to oscillate about the shaft axis Ax through an angle alpha to cause relative motion between the interdigitated coil/core assemblies (12) and superpoles (10). The coil assembly (24) includes a plurality of radially aligned spokes (36), each of which carries a coil/core assembly (12) defined by a wound coil (18) and an associated laminated core (20). The magnet array (28) is supported for limited oscillatory motion about the shaft axis and is defined by a cylindrical support shell or case (42) from which the superpoles (10) are mounted in a radially aligned manner with the superpoles (10) positioned in an interdigitated manner with the coil/core assemblies (12). In operation, the magnet asembly (28) is caused to oscillate about the machine axis Ax to cause each superpole (10) to move toward and closely approach its adjacent coil/core assembly (12) and then reverse its motion and then move toward and closely approach the coil/core assembly (12) on its opposite side. As a consequence of this motion, an alternating electric current will simultaneously flow in all the coil/core assemblies (12).
