  • Electrical Considerations of Fan Cooling
    . The standard fan supplied with the amplifiers is a 12V brushless DC motor fan. Like all switching circuits the brushless motor commutation generates electrical noise. If care is not taken in how the fan is connected to the amplifier circuit some of that electrical noise may appear at the output
  • 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
  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    on or completely off. This efficient control methodology affords a very wide speed control range (typically 10% to 100% of full speed) because the fan motor is exposed to its full-rated voltage during the active portion of the PWM cycle. PWM control works with standard, two-wire Brushless DC (BDC) fans
