  • AC Induction Motor Fundamentals
    induction motors are available in the market. Different motors are suitable for different applications. Although AC induction motors are easier to design than DC motors, the speed and the torque control in various types of AC induction motors require a greater understanding of the design
  • An Introduction to AC Induction Motor Control Using the dsPIC30F MCU
    This application note demonstrates how you use the dsPIC30F MCU to control an AC Induction Motor (ACIM). The discussion is based on the dsPICDEM MC motor Control Development System, but you can use your own hardware if you choose. The dsPICDEM MC Motor Control Development System has electrical
  • AN1162 - Sensorless Field Oriented Control (FOC) of an AC Induction Motor (ACIM)
    AN1162 Sensorless Field Oriented Control (FOC) of an AC Induction Motor (ACIM) operate at a speed that is roughly proportional to the Author: Mihai Cheles input frequency. As you decrease the frequency of the Microchip Technology Inc. drive voltage, you also need to decrease the amplitude Co-Author
  • Dc motor impersonators
    Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. The rotating speed of ac induction motors is determined by the frequency of ac applied to the stator, not the applied voltage. However, stator voltage must also drop to prevent excessive current
  • Understanding Electronic Motor Drives
    drive controls the speed, torque, direction, and resulting horsepower of a motor. Dc drives typically control a shunt-wound dc motor, which has separate armature and field circuits. Ac drives control ac-induction motors and, like their dc counterparts, control speed, torque, and horsepower
  • Smart Air Handler using ProMPT TM and the PIC18F2539
    reduced cost of operation. This application note discusses the implementation of a variable speed air handler that utilizes a single phase AC induction motor. The task of designing the variable speed air handler is greatly simplified by using the Microchip Programmable Motor Control Processor Technology
  • Eliminating sensors from closed-loopcontrol
    . Here's how encoderless systems compare with more traditional motor-control methods. To operate efficiently, a conventional flux-vector PWM drive needs to know the rotor flux angle inside an ac-induction motor. A pulse encoder typically supplies information about rotor speed and angular position
  • Rotary encoders for motors
    Constant-speed ac-induction motors don't really hold a constant speed. In an optical encoder, an LED typically shines light through a code disk and mask to illuminate a photodetector assembly. The slots in the disk and mask form a shutter that passes or blocks the light beam as the code disk
