ABSTRACT:
A reciprocating magnetic body support structure for a linear motor or a linear alternator is claimed. The body comprises a cylindrical, metallic support sleeve having a plurality of longitudinal slots evenly spaced around the circumference of the sleeve. An equal number of magnet segments is mounted to the sleeve extending over at least a portion of the associated slot and attaching to the wall of the sleeve on both sides of the associated slot. The longitudinal slots preferably extend completely through the sleeve from near one longitudinal end of the sleeve to near an opposite longitudinal end of the sleeve. The sleeve is preferably stainless steel or titanium, but should, regardless of metal, have a high resistivity, i.e., above 50 micro ohms per centimeter.
