  • Brushless DC Motors
    motors generally contain a three-phase winding, although some operate four phase. Brushless motors powering small fans and other constant-speed equipment are often two phase. Power for brushless motors generally is a trapezoidal ac wave form, but some of the motors operate with sine waves
  • Brushless dc Motors in Medical Applications
    for equipment with greater throughput and high reliability. To accomplish this goal, drive train components must provide more torque over expanded speed ranges and at higher duty cycles. Compared to brushed-dc motors, brushless-dc motors do exactly that. As medical equipment grows smaller and lighter
  • Reducing cogging torque in brushless motors
    Brushless dc motor windings are similar to the windings in a multiple-phase ac motor. But brushless motors also contain a permanent --magnet rotor and a sensor to detect the rotor position to produce signals that control electronic switches for commutation. The most common position sensor

    and are quite challenging for manufacturers. Without the use of more advanced electronic technology these standards may be potentially impractical. Such technology includes variable-speed drives powering either a standard ac induction or brushless dc compressor. Modern air conditioners incorporate power factor
  • Brushless DC Motor Control Using PIC18FXX31 MCUs
    A PICDEMTM MC demo board was used to develop, test and debug the motor control code. The PICDEM MC has a single-phase diode bridge rectifier, converting AC input to DC and a power capacitor bank that keeps a stable DC bus. A 3-phase IGBT-based inverter bridge is used to control the output voltage
