Abstract

The limited angle torque motor (LATM) is an electromagnetic actuator that rotates within a limited angle of less than ±90°. In this study, the advantages of permanent magnet (PM) type and reluctance type LATM are combined to create a hybrid LATM with high torque density for the same volume. The proposed hybrid LATM structure combines structural advantages using a PM with a high magnetic flux density of a PM type LATM and voice coil winding with a high fill factor of reluctance type, as well as making a prototype and conducting a torque test.
