Abstract :
Brushless DC (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have a low cost, but effective BLDC motor speed/torque regulator. This paper introduces a novel concept for digital control of trapezoidal BLDC motors: conduction-angle control. The controller is very simple to implement in a cost effective application-specific-integrated-circuit (ASIC). The controller design equations are derived from Newton´s 2nd law. The novel controller is verified via computer simulations and an experimental demonstration is carried out with the rapid prototyping and real-time interface system, dSPACE
