  • 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
  • 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
  • Incompatibility of Power Factor Correction Capacitors with AC PWM Drives
    Usage of power factor (P. F.) correction capacitors is commonplace on many induction motors used on constant speed (across-theline) applications. A fixed KVAR (Kilovolt-Amp-Reactance) value of capacitors is sized to counteract the motor's inductive reactance, thereby raising the overall power
  • Stepper Motor Control Using the PIC16F684
    between full steps and to improve the step resolution of the motor. Microstepping also This application note describes how to drive a bipolar improves the efficiency of the system, because the stepping motor with the PIC16F684. The Enhanced current in the windings of the motor is manipulated
  • 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
  • Braking and Regenerative Energy with AC Drives
    What is Regenerative Energy? When a motor turns faster than the commanded speed as set by its AC variable speed drive, the motor in effect acts as a generator. An example of this would be the control of an elevator car as it descends. With the help of gravity, the load will readily lower. In fact
  • Motor Control in Home Appliances
    The home appliance market uses three-phase, pulse-width-modulated (PWM) motors in a number of end applications including air conditioners, washers, dryers and garage door openers. Many of these applications require variable speed and/or torque, and the controllers that provide this capability must
