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 ...

Tony Goacher] has worked with a lot of cheap brushless DC motor controllers built in China. They can be very cost-effective, ...

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.
