  • Dc motor impersonators
    . Audio / Videos. Training Center. Whitepapers. Reference Centers. Dc motor impersonators. July 27, 2006. Robert Repas. Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. Printer-friendly version. The rotating speed of ac induction motors
  • Selecting DC Motors
    commercial magnet now available. High MEP comes at a premium and should not be lost to temperature extremes. Neodymium magnets are continually being improved with lower temperature coefficients to make them as stable as other rare-earth grades. Peak loads applied to AlNiCo and ceramic dc motors can
  • Brushed DC Motor Fundamentals
    Brushed DC motors are widely used in applications ranging from toys to push-button adjustable car seats. Brushed DC (BDC) motors are inexpensive, easy to drive, and are readily available in all sizes and shapes. This application note will discuss how a BDC motor works, how to drive a BDC motor
  • PM DC Motors
    . In comparison, the most widely used ferrite magnets only have an MEP of 1.8 to 4.5 MGOe. Rare-earth magnets make for small, lightweight motors with up to 50% more torque than ordinary ones having comparable dimensions. This allows a smaller rare-earth motor to do the job of a more expensive and larger
  • Brush DC Motor Basics (.pdf)
    . The design of the low inertia rotor enables. very high acceleration and fast reaction time. Finally the linear torque-speed characteristics make the motor very easy to. drive. This article is a brief technical introduction on ironless DC motors. It is intended to help engineers to better understand
  • 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
  • Sensorless Brushless DC Motor Control with PIC16
    Control" (DS01178) while one-phase motors are a degenerated form of two-phase motors. BACKGROUND For a full description of three-phase brushless motors,. 01175A.book AN1175. Sensorless Brushless DC Motor Control with PIC16. MOTOR CONTROL. Author: Joseph Julicher. Dieter Peter. BLDC motor
  • Machine Optimization through DC Motor Selection (.pdf)
    , where they fit best, and how to decide which to use in your application. DC motors are being used in more and more industrial applications because of their flexibility and long life. Therefore, DC motor selection is often one of the most important steps in providing motion control of a medical machine
