Title:
Sinusoidal Current Drive for Brushless DC Motor
Name:
AN2557
Date:
11/16/2017
Author:
Mike Gomez, Mark Pallones
Description:
Sinusoidal current drive is known to deliver improvements in performance in terms of motor vibration and acoustic noise. Motor controls may therefore use a sinusoidal current drive in preference to the traditional rectangular/square current drive given that overall system implementation cost should be analogous with the complexity of motor design. In this application note, 8-bit PIC® microcontroller will be used to implement sinususoidal current drive on a low cost single-phase or 2-phase (Split Phase) BLDC Motor with sensored or sensorless mode.
