  • Solid-State ac Power Sources for Transformer Testing
    High-power electronics can now replace motor-generator sets for testing distribution transformers. * Solid-state ac-power sources combine the variable-frequency and voltage-power sources into a single package. * Tests sets are hardened against impulse events like those caused by lightning-strike
  • Brushless DC Motors
    motors generally contain a three-phase winding, although some operate four phase. Brushless motors powering small fans and other constant-speed equipment are often two phase. Power for brushless motors generally is a trapezoidal ac wave form, but some of the motors operate with sine waves
  • Dc motor impersonators
    , during a 2 motor speed increase. The curve duplicates the armature current for a dc motor performing the same operation. The net effect provides dc motor control response for ac induction motors. Synchronous dc motors often top the field in high-performance motor controls. This group of motors includes

Instead, the. current in the field coil and the armature are indepen-. commutation of the windings of a BDC motor is done. dent
  • Mathematics of Electronic Motor Control
    control of multi-phase motors. The AC induction motor is the workhorse of most household goods because it is easy to control and is very low-cost. In its simplest configuration it plugs directly into the wall with a minimum of electronics in the motor. But to increase motor efficiency and improve

    windings or phases, similar to a 3 ac motor. But without a sensor to detect the rotation angle of the permanent magnet in the rotor, it’s impossible to know which phases to energize with a given polarity. The most common technique starts by energizing two of the phases with a given polarity. Current

  • Sensored BLDC Motor Control Using dsPIC30F2010
    The dsPIC30F2010 is a 28-pin 16-bit MCU specifically designed for embedded motor control applications. AC Induction Motors (ACIM), Brushless DC (BLDC) and DC are some typical motor types for which the dsPIC30F2010 has been specifically designed. In this application note we discuss how
