How Less Can Be More in Motor Control Design

 

How Less Can Be More in Motor Control Design
The automobile is knee-deep in low-voltage DC motors throughout the vehicle’s framework. When creating an automotive BLDC motor system, the primary control challenge is to measure motor’s position and torque. This article defines DC motor signal dynamics and a new effective high PWM rejection Current-Sense-Amplifier (CSA) that has fast settling time accuracy to complement faster motor control algorithms.
