  • 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
  • Sensorless Field Oriented Control of PMSM Motors using dsPIC30F or dsPIC33F Digital Signal Controllers
    is specifically. software-based implementation of sensorless, field ori-. designed to control the most popular types of motors,. ented control for permanent magnet synchronous. including: motors using Microchip digital signal controllers. • AC Induction Motors (ACIM). The control software offers
  • Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function
    and high efficiency. Increasingly, it is also This application note describes a sensorless Brushless used in automotive applications as a part of strategy to Direct Current (BLDC) motor control algorithm that is eliminate belts and hydraulic systems, to provide (R) Digital Signal Controllerimplemented
  • 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
  • Integrated Drive Electronics for Brushless DC Motors
    to supply logic signals to the controller. This sytem lends itself to the generation of precise. angular encoding signals and is often specified where greater resolution is desired. Sensorless drives represent one of the newer methods to achieve commutation in BLDCs, although. applications
  • Medical Device Link .
    . Miniature motor A 0.007-in.-diam brushless motor and planetary gearhead is the world's smallest available gearmotor, according to its manufacturer. The BL 1900 series uses a bipolar rare-earth permanent magnet for the motor rotor, Liga cast gears in its gearhead, and a sensorless electronic commutation
