Multi-vector electronic control of an AC motor drive reduces torque ripple and improves efficiency
By suppressing or controlling harmonic currents and voltages of the motor to overcome torque ripple, this system improves the efficiency and torque performance of an AC motor, especially permanent magnet synchronous motors (PMSM), which are very popular in industry due to high efficiency and small volume compared to other types of motors. Many PMSMs use a concentrated winding for the benefit of simple manufacturing and low cost, and they have a large spatial harmonics. PMSMs are controlled by conventional vector control drives, but voltages and current harmonics present in the motor can deteriorate accuracy and efficiency. Compared to conventional vector control, this technique further improves efficiency and torque performance by reducing the harmonics. This technique can be used in many types of equipment, including trucks and other vehicles, elevators, washing machines, air conditioners, machine tools, robotics, and industrial equipment where quick response and accuracy in speed or position control are required. The technique is simple to implement, and may be applied to existing equipment.efficiency PMSM electric motors two potential outcomes realized
