Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

As recently as two years ago, brushless motors were significantly more expensive than brush motors. However, advances in design and materials have triggered dramatic price drops in brushless motors.

How current-control loops in BLDC motors improve performance and efficiency while protecting against overcurrent conditions. The differences between current-control loops, field-oriented control (FOC) ...
