Commutation system for torque ripple minimization

Commutation system for torque ripple minimization

A system for reducing torque ripple in an electric motor, comprising an electric motor having a stator and a rotor, a first set of N Hall sensors, a second set of N Hall sensors, a controller, and wherein said N Hall sensors in each said set of Hall sensors is spaced 360/N electrical degrees apart a...

Zusammenfassung:A system for reducing torque ripple in an electric motor, comprising an electric motor having a stator and a rotor, a first set of N Hall sensors, a second set of N Hall sensors, a controller, and wherein said N Hall sensors in each said set of Hall sensors is spaced 360/N electrical degrees apart and said first and second sets of Hall sensors are spaced T electrical degrees apart, and wherein said controller is adapted to provide increased current during an overlap period detected by said Hall sensors.
