Loss analysis for the hybrid linear switched reluctance motor with no cogging force

Linear motors are suitable for direct-drive applications in industry. To improve the performance of pure linear switched reluctance motors (LSRMs), permanent magnets (PMs) are introduced to the magnetic circuits [1-3]. Loss of the PM-type linear motors are discussed [2]. Two possible ways of cogging force reduction are investigated [3]. Analytical prediction and measurement for quantifying iron loss in a tubular PM machine are described in [4].
