  • Sensorless Brushless DC Motor Control with PIC16
    AN1175 Sensorless Brushless DC Motor Control with PIC16 MOTOR CONTROL Author: Joseph Julicher Dieter Peter BLDC motor control consists of two parts. Part 1 is Microchip Technology Inc. commutating the motor at the most efficient rate. Part 2 is regulating the speed of the motor within defined
  • Electric Fans Brushless DC Motor
    Most of the electric fans on the market now use traditional AC motors, which have a limited service life, inconvenient maintenance, high energy consumption, and low motor controllability. To satisfy people in different usage scenarios and different usage environments, a wide range of adjustable
  • Speed Error in PWM Fan Control Systems
    Brushless DC fan (BDC) speed can be varied using pulse-width modulation (PWM). The typical PWM control scheme inserts a power switch in series with the fan, as shown in Figure 1. In such applications, an increase in the active duty cycle causes a corresponding increase in fan speed (i.e., fan speed
  • Electric Fans Brushless DC Motor Solutions
    Power Motor will continue to optimize the fan motor solution, so that it is smaller, lighter, more environmentally friendly and energy saving, to meet the fan intelligent control, stepless speed regulation, lightweight, energy saving and environmental protection trend.
  • Brushless DC Motor For Electric Fans Solutions
    on for a long time, its energy consumption, noise, and wind speed are the most direct criteria for considering the product. For electric fan products, the motor is one of the most important components. Most of the electric fans on the market now use traditional AC motors, which have a limited
  • 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
  • An Integrated Fan Speed Control Solution Can Lower System Costs, Reduce Acoustic Noise, Power Consumption and Enhance System Reliability
    of a few years, technological and other developments have made thermal cooling necessary for many applications, thus requiring the development of a new system management category: thermal management.This article discusses an integrated fan speed solution that provides sophisticated speed control
  • Using the dsPIC30F & dsPIC33F DSCs for Sensorless BLDC Control
    application for using the are possible with software modifications. dsPIC30F to control brushless DC (BLDC) motors Hard modulation of diagonally opposite inverter without position sensors. The software makes switches is supported. extensive use of dsPIC30F peripherals for motor control. The algorithm
