This paper presents a moving-magnet type linear actuator designed by using flux concentration type permanent magnet arrangement, which can generate higher magnetic flux density in air-gap. In this construction, detent force which is induced by both slot-effect and end-effect becomes larger due to strong attractive forces. To reduce cogging force we have employed a modular mover structure of two magnetic...
This paper presents the design and analysis of a zero cogging halbach array permanent magnet Brushless DC motor (PMBLDC) meant for spacecraft applications. The design of the zero cogging BLDC motor requires the choice of slotless configuration. Three types of machine configurations, Slotless PMBLDC with radial, parallel and halbach magnetization were compared and analyzed using analytical models....
This paper presents effect of magnet arrangement on torque characteristics of a magnetic flux concentration type surface magnet motor. Some constructions of the permanent magnet array were tried to reduce the cogging torque. Their magnetic flux distributions and torque characteristics were calculated by using the finite element method.
