  • Encoders for Brushless Motor Commutation
    The process of steering current through the appropriate motor windings in order to produce output torque is called commutation. In brush motors, commutation is accomplished electro-mechanically via brushes and the commutator. In brushless motors, commutation is performed by electronically steering
  • Sinusoidal Commutation of Brushless Motors (.pdf)
    This application note includes a complete discussion of brushless motors. Part One is. devoted to an in-depth review of both brush- and brushless motor theory. Part Two. relates brushless commutation using a Galil Motion Controller. Part Three includes. some real-world cases of brushless motor
  • Brushless DC Motors
    . The situation has brought a large number of competitors into the market, helping to reduce prices for brushless systems. A result is that brushless motor sales have risen rapidly in the last few years. And sales of brushless motors continue to increase. come in a variety of configurations. The most
  • Brushless dc Motors in Medical Applications
    for more-efficient, compact, and reliable medical equipment has put BLDC motors on the prescription list for a variety of applications. By definition, a brushless-dc motor is a synchronous electric motor powered by a dc-power source. While derived from the brushed-dc motor, an electronic commutation
  • Brushless DC (BLDC) Motor Fundamentals
    Brushless Direct Current (BLDC) motors are one of the motor types rapidly gaining popularity. BLDC motors are used in industries such as Appliances, Automotive, Aerospace, Consumer, Medical, Industrial Automation Equipment and Instrumentation. As the name implies, BLDC motors do not use brushes
  • 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
  • Setting up a brushless commutation with Galil's built-in 500W servo drives
    A 3-phase brushless motor requires the amplifier to provide electronic commutation. Commutation of a brushless motor means that the amplifier needs to decide which phase of the motor to energize and at what point in the magnetic cycle to energize it. Standard Galil 500W amplifiers require hall
  • 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
