Motor Control Algorithms

Motor Control Algorithms commonly used on Microchip MCUs and Digital Signal Controllers.

Algorithm Applicable Motors Notes
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
Field Oriented Control
(with sensored feeback)
PMSM, BLDC High efficiency
Excellent torque control
Six-step Trapezoidal
(with sensorless feedback )
Good torque control at moderate and high speeds
Six-step Trapezoidal
(with sensored feedback )
PMSM, BLDC Good torque control at all speed ranges
Six-step Sinusoidal PMSM Low noise
Open Loop (V/F) ACIM Low cost
