  • 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
  • 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
  • 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
  • Commutation of a BLDC Motor with Various Pole-Pairs Can Be Simplified By Using Absolute Encoder Feedback - White Paper (.pdf)
    Brushless Direct Current (BLDC) motors are gaining popularity and larger market acceptance. BLDC motors are used in industries such as Industrial Automation Equipments, Consumer, Medical, Automotive, Aerospace and Instrumentation. BLDC motors do not use brushes for commutation; instead
  • Motor Type Selection
    Parameters that define a motor type are the mechanical output power, the shaft bearing system, the commutation system used, and the possible combinations with gearheads and sensors. The most important criteria include the speed and torque requirements, and the commutation system

  • Using the dsPIC30F & dsPIC33F DSCs for Sensorless BLDC Control
    of the electrical cycle. (The sector numbering. - Relies on characteristic bus current shape. is completely arbitrary but matches that used. due to commutation changing as rotor. throughout the software.) Commutations occur at the. leads/lags. boundary of each of the sectors. Therefore, it is the. - Can not use
  • Brushless DC (BLDC) Motor Fundamentals
    for commutation; instead, they are electronically commutated. BLDC motors have many advantages over brushed DC motors and induction motors. In addition, the ratio of torque delivered to the size of the motor is higher, making it useful in applications where space and weight are critical factors
