Abstract
A direct-drive type annular flexible transportation system and a collaborative control method thereof are provided. The direct-drive type annular flexible transportation system includes an annular base, a primary excitation type linear motor, an power supplying module, a power driving module, a position detection module, and a wireless communication module. The primary excitation type linear motor includes a long stator and a plurality of movers. The long stator is formed by connection of stator iron cores presenting a multi-segment cogging structure and is installed on the annular base. Each of the movers includes a short primary, a power driving module, a position detection module, and a wireless communication module. The short primary is formed by an asymmetrically-structured permanent magnet array, an armature winding, and a primary iron core.
