Abstract:
This paper presents the finest design of an exterior mounted Permanent Magnet Brushless DC motor meant for various applications. Some applications require the selection of a torques motor with elevated torque density, least cogging torque, enhanced positional stability and high torque to inertia ratio. The Slotless type of halbach array develops zero cogging torque and high developed torque and to provide dramatic improvements in consistency, maintainability, supportability and cost as well as enhancements in different applications. Furthermore, the machine life forms coreless to provide high torque to inertia ratio and zero magnetostriction.
