The switched reluctance motor (SRM) has recently received much attention because of its preferred features in simple and rugged configuration and elimination of permanent magnet (PM).
In this paper, a direct-drive spherical motor to produce two-degree of freedom rotations has been proposed. The structure and prototype of the motor are given and the basic principles are described, including the operation principle and mathematic theories, etc. Importantly, the two air gaps between the mover and the rotor, the mover and the stator that mainly determine the performance of the motor...
Linear permanent magnet motors (LPMM) and linear switched reluctance motors (LSRMs) are suitable for translational, direct-drive position control applications. Several linear permanent magnet motors (LPMMs) have been investigated [1-3]. However, there often exists unavoidable cogging forces from LPMMs that require additional control algorithms to compensate for high-precision, position control applications...
Linear motors, as direct-drive actuators, have been quickly developed within recent years and now they are widely applied in the industrial production area, such as automatic soldering, carving and embroidery machines, etc [1]. At present, linear permanent magnetic motors (LPMMs) are the mainstream of market due to their considerable force output performance with high power density and efficiency...
