  • Using the dsPIC30F & dsPIC33F DSCs for Sensorless BLDC Control
    implemented for sensorless The system supports motoring in closed-loop control is particularly suitable for use on fans and commutation as would be required for a typical pumps. The program is written in C and has been fan or pump. specifically optimized and well annotated for ease of understanding
  • Sensorless Brushless DC Motor Reference Design
    motors are much. EMF of the motor and using this information to control easier to start than sensorless BLDC motors. The. the commutation of the motor. complexity of starting a fully loaded BLDC motor often. makes the ac induction motor a better choice,. particularly for piston pumps and compressors
  • Sensorless BLDC Control with Back-EMF Filtering
    negative. sensorless algorithm described in this application note. Blue winding is not driven. is six-step trapezoidal or 120° commutation. Figure 5. 2. Red winding remains positive. shows how six-step commutation works. Each step, or. Blue winding is driven negative. sector, is equivalent to 60
  • Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function
    commutation rate for the applied voltage solution, which does not requires external hardware * Commutation at rates faster than the ideal rate except for a couple of resistors used to conditioning the will. Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function AN1160. Sensorless
  • Sensorless Switched-Reluctance Generators: a Technology Read for Aerospace Applications
    still present mechanical integrity at speeds faster than 100,000 rpm. SensorlessSR_2790-01 R. Content appeared in the October 2002 issue of. Sensorless switched-reluctance generators: a technology ready for aerospace applications. by Dr. Babak Fahimi, member IEEE, Dr. Raymond B. Sepe Jr
  • 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
