【Abstract】 To explore the characteristics of the connected permanent magnet synchronous motor during operation, an analysis is conducted on the connected motor from both magnetism and steady-state voltage vector relationships. The main structure and working principle of the connected permanent magnet synchronous motor were introduced. Based on this, the equivalent magnetic charge method was used to calculate the interaction force between the magnetic poles on both sides of the connected motor, revealing the characteristics of the interaction between the two individual magnetic poles of the connected motor. Based on the voltage vector diagram drawn by the equivalent circuit of the motor, the steady-state characteristics of the connected motor were analyzed, and the stable control region of the connected motor was proposed. To control the connected motor through the overall stator voltage and current, a unified model of the connected motor was established and the unified voltage equation of the connected motor was given. A 0.5 kW stator connected dual axis permanent magnet motor prototype was validated, and the simulation and experimental results prove the correctness of the analysis results.更多还原
