Because of wide adaptability of its product, ring spinning frame is widely used. Motor-driven spindle is organic combination of traditional spinning frame spindle and high speed permanent magnet brushless DC motor (BLDCM). Compared with the traditional ring spinning frame, motor-driven spindle type ring spinning frame can detect the yarn state automatically, which is conducive to improve the quality of yarn, so it is the future development direction of ring spinning frame. Therefore, in this paper, the motor-driven spindle drive and management technology of ring spinning frame is researched. Base on full understanding of ring spinning frame working principle, advantages and benefits of motor-driven spindle drive and management technology on ring spinning frame is analyzed, some opinions on design of brushless DC motor, which is the motor-driven spindle key component, are presented, then mathematical model and control system model based on Matlab/Simulink of motor-driven spindle motor are derived. Whereby, this paper provides analytical results on mechanical properties of different mechanical characteristics of motor operating point of the conduction angle of the leading and lagging. At last, this thesis introduces related factors of motor-driven spi
