  • Understanding Electronic Motor Drives
    magnitude voltage pulses. All PWM drives contain an input converter, dc bus, and output inverter. For simplicity, only one phase of input and output are shown for a 3-phase drive. Selecting the right drive is essential to getting the best performance and efficiency from an electric motor. A motor
  • Using AC PWM Drives on Non-Standard Voltages and Frequencies
    a tremendous advantage in its ability to stay in regulation at lower than nominal voltage levels. The design input voltage tolerance is stated as + /- 10%, although the drive's line dip trip threshold is well below this specification. Motor HP will suffer if voltage is reduced below 90% of its

  • DC Motor Application Considerations
    switching results in radiated noise from motor lead wires. Shielding and lead wire placement can also help mitigate the effect of PWM generated EMI.
  • Power and efficiency drive motor selection
    motors are 30% more efficient, use 20% less power, and are 2/3 the size of ordinary BLDC motors. They come in sizes from 60 to 110 W and include onboard PWM drive electronics with tachometers to lower distortion. Output power and overall efficiency are key parameters to consider when sizing motors
  • Stepper Motor Control with dsPIC (R) DSCs
    This application note describes how to drive a stepper. motor with a dsPIC33F motor control family DSC. The eight PWM channels (six pins from the PWM1. module and two pins from the PWM2 module) are used. to control a stepper motor in all possible ways, whether. it is bipolar or unipolar, using full
