  • Industrial Three Phrase Electric Actuators
    In an industrial environment with three phase power readily available, there are several reasons three phase power just. makes good sense. The main reason to use a three phase motor is that it runs more efficiently than a comparably sized single phase motor. This translates to the motor running
  • Comparing Three-Phase Power Measurement Instruments
    Teledyne LeCroy's Motor Drive Analyzer (MDA) provides three-phase power measurements comparable to a power analyzer using its eight 12-bit input channels. This brief summarizes how to correctly compare Yokogawa's power analyzer instrument to the MDA, and to explain any differences in measurement
  • Why Three Phase Induction Motors Are Popular for Industrial Applications
    Three phase induction motors have been a popular choice for many industrial applications for a number of reasons: *Non-complex construction - they don't require permanent magnets, brushes or windings on the rotor. *They run directly off of the electric distribution grid. *Low cost. *Rugged
  • Will the Small Motor Rule Affect You?
    for Open Drip Proof, General Purpose motors in both single and three phase designs. Dubbed the Small Motor Rule, horsepower ratings covered include 0.25 thru 3 HP (and kW equivalents) with speed ranges of 1,200 - 3,600 RPM operating from 60 Hz frequency.
  • Sensorless Brushless DC Motor Control with PIC16
    to dissipate heat in the BLDC * Reduced audible and electromagnetic noise All BLDC motors require three half-bridge driver stages. Each stage controls one phase of the motor, as There are many different types of brushless motors, illustrated in Table 1 below: and the differences are: - The number of phases
  • Sensorless Brushless DC Motor Reference Design
    designers using Silicon Laboratories MCUs, significantly reducing the design time and time to market. Brushless dc motors consist of a permanent magnet rotor with a three-phase stator winding. Brushless dc motors evolved from conventional dc motors where the function of the brushes is replaced
  • 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
  • CMOS Isolators for Home Appliance Motor Control
    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
