A new space vector pulse width modulation(SVPWM) technique for the dual Y shift 30° permanent magnet synchronous motor(PMSM) is presented.Intuitive and straightforward approach for analytical investigation of the harmonic characteristics in the stator windings lend to analytical formulas of square rms harmonic current and modulation index.This PMSM control system is set up based on a low-cost fixed-point TMS320F2812 digital signal processor.The experimental results demonstrate the effectiveness and feasibility of the proposed method.
