Abstract


The inherent weaknesses of the DC motor , to promote the rapid development of the AC motor drive . Occasions in high-power and high reliability , multi-phase motor has unique advantages , many scholars research interests turned to multi-phase motor . Although the multi-phase motor body showed good performance , but its control than the three-phase AC motor system more complex. In this paper, the characteristics of the multi-phase induction motor speed control system were reviewed and summarized , a novel control method is proposed : the six-phase induction motor trapezoidal wave phase current control . Phase of the trapezoidal wave current is determined by the excitation current and torque current of the excitation winding and the torque windings , analog DC motor to achieve the direct control of the excitation magnetic field and torque can be divided into six-phase stator winding in the next phase of the trapezoidal wave current drive , without complex coordinate transformation . First, create a mathematical model of the six-phase induction motor dq rotating coordinate system , analysis of rotor field oriented control under the six-phase induction motor control system . Analysis of six-phase induction motor trapezoidal wave phase current drive motor performance. Calculate the the MMFs balance corresponding to the value of K , the derivation and analysis of the six-phase induction motor electromagnetic torque equation . Calculated air gap MMF harmonics and every phase of the self-inductance and mutual inductance and winding function . Secondly , the use of Matlab simulation software , to establish the model of the trapezoidal wave phase current drive under the six-phase induction motor drive system , dynamic analysis system and static performance . Finally, converted into a small six -phase induction motor , the establishment of a trapezoidal wave phase current drive under the six - phase induction motor drive system experimental platform to verify the theoretical analysis and Matlab simulation results . Simulation and experimental results show that : the drive system in the MMFs balance or zero orthogonal magnetic flux conditions , torque and the torque current to remain linear relationship and is independent of the load ; under the control of the trapezoidal wave phase current , good electromagnetic torque response speed.
