Dual three-phase induction motor power loss analysis with its modeling and simulation of vector-controlled system

摘要

Dual three-phase induction motors (DTPIMs) have a higher power density and reliability, but a more complicated magnetic coupling than traditional three-phase induction motors. In this paper, a DTPIM fed by a sinusoidal power source and a PWM power source is analyzed by the time-stepping finite element method (FEM). In order to apply vector control to the motor, the six phase windings of the stator are divided into two perpendicular sets of windings by the rotor flux orientation method, making it possible to control the excitation current component and the torque current component, respectively. The speed and current loops are also established in MatLab to improve the performance of the proposed motor. The variable-load operation is implemented in the simulation of the vector controlled DTPIM. Simulation results show that the proposed motor can generate desired torque and speed output.
