  • Brushless dc Motors in Medical Applications
    Just What the Doctor Ordered: Brushless-dc Motors Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. * Sensorless brushless-dc-drives have evolved to a point where they have wide appeal within the medical-design
  • Integrated Drive Electronics for Brushless DC Motors
    Brushless DC motors (BLDCs) achieve commutation electronically by utilizing a permanent-magnet. rotor, wound stator, and rotor-position sensing scheme instead of a mechanical commutator or brushes. found in brush-type DC motor designs. With brush wear or arcing eliminated and as a result of other
  • A Practical Guide to Brushless DC Implementation
    in their variable speed applications. Drive & Motor Connection - The market for BLDC drives and motors is fragmented – evidenced by the number of companies who list themselves as Motor Manufacturers (133) and Brushless DC Drive Manufacturers (50)1.  There is little standardization in terms of motor wire
  • Brushless DC Motor Control Made Easy
    This application note discusses the steps of developing several controllers for brushless motors. We cover sensored, sensorless, open loop, and closed loop design. There is even a controller with independent voltage and speed controls so you can discover your motor's characteristic's empirically
  • Sensorless BLDC Control with Back-EMF Filtering
    This application note describes a sensorless brushless DC (BLDC) motor control algorithm, implemented using the dsPIC(R) digital signal controller (DSC). The algorithm works by digitally filtering the back-Electromotive Force (back-EMF) on each phase of the motor and determining when to commutate
