Types of Motor Control Algorithms

Motor control algorithms are commonly used on Microchip MCUs and Digital Signal Controllers (DSCs).

AlgorithmApplicable MotorsNotes
Field Oriented Control
(with sensor-less feedback)
Permanent Magnet Synchronous Motor (PMSM), Brushless Direct Current (BLDC), AC Induction Motor (ACIM)High efficiency
Excellent torque control
Low cost
