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 ...

AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...
