  • Selecting Dc Brush and Brushless Motors
    whether to employ brushless or brushed dc, or stepper motors. Stepper motors are generally considered specialpurpose devices because they can't handle large inertial loads very well. And operation near their maximum torque ratings can take some finesse. * Shaft-bearing systems, commutation, and motor...
  • Integrated Drive Electronics for Brushless DC Motors
    Brushless DC motors (BLDCs) achieve commutation electronically by utilizing a permanent-magnet. rotor, wound stator, and rotor-position sensing scheme instead of a mechanical commutator or brushes. found in brush-type DC motor designs. With brush wear or arcing eliminated and as a result of other...
  • Sinusoidal Commutation of Brushless Motors (.pdf)
    , but the term "brushless" is given to a group of motors that act similarly to DC-. brush type motors without the limitations of a physical commutator. To review, a DC-. brush motor consists of a wound rotor that can turn within the magnetic field as provided. by the stator, as shown in figure (9). By including...
  • Intelligent Thermal Management Using Brushless DC Fans
    The brushless DC fan (BDC Fan) has become the air mover of choice in computing equipment, office automation products, home entertainment systems, and the like. Unlike conventional DC fans, the BDC fan is mechanically robust because it contains no rotating commutator/brush assembly to shed dust...
  • Optimizing dc-brushless servomotors
    outside the familiar envelope. To find an optimal motor solution then, requires a return to basic principles. Consider dc-brushless servomotors, for example. Optimized dc-brushless servomotors respond faster, deliver higher torque at lower speed, and use less current than nonoptimized designs...
  • Dc motor impersonators
    brushed, brushless, wound-field, and permanent-magnet varieties. They are widely used simply because it's easier to regulate the operation of dc motors than that of ac motors. This is especially true if the application demands tight control of motor torque, velocity, or position. Within specific...

  • A New Absolute Inductive Transducer for Brushless Servomotors
    Today, frameless brushless (pancake) resolvers are commonly used on AC and brushless DC servomotors to provide commutation, position, and velocity information to the servo controller. These angular position transducers give a constant signal representing the absolute position of the motor shaft...
  • Torque motors do the trick
    to frame sizes for conventional brushless-dc servomotors. For each diameter, there are several axial lengths, so engineers have a range of sizes to satisfy torque requirements for given applications. A torque motor is part of this rotary table Torque motors have been around since at least 1970...
