Motor Control
Back Electromotive Force (Back-EMF)
Back-EMF is the voltage a spinning motor generates in opposition to the voltage driving it.
Motor Control
Field Weakening
Field weakening limits effective motor flux at high speed so back-EMF stays within inverter voltage.
Motor Control
Field-Oriented Control (FOC)
FOC separates motor-current components so controllers can regulate torque and magnetic flux precisely.
Motor Control
Pulse-Width Modulation (PWM)
PWM controls an inverter's average output voltage by changing semiconductor switch-on times.
