  • Sizing Three-Phase Inverters for Single-Phase Power Applications (.pdf)

    of thumb Hitachi recommends is to start with the 3-phase motor’s nameplate full. load amperage (FLA) rating and double it. Then select an inverter with this doubled. continuous current rating. This will give adequate margin in the input rectifier bridge and. bus capacitors to provide reliable performance

  • VFD Motor Testing (.pdf)

    . Positive, negative and zero sequence harmonics exist in all 3-phase systems. Positive sequence harmonics create a magnetic field in the direction of rotation. The magnetic field. developed by the fundamental harmonic (60 Hz) must be in the direction of rotation. Otherwise, the motor would run backwards

  • Study helps unlock mystery of high-temp superconductors

    (Binghamton University) A Binghamton University physicist and his colleagues say they have unlocked one key mystery surrounding high-temperature superconductivity. Their research, published this week in the Proceedings of the National Academy of Sciences, found a remarkable phenomenon in copper-oxide (cuprate) high-temperature superconductors.Michael Lawler, assistant professor of physics at Binghamton, is part of an international team of physicists with an ongoing interest in the mysterious pseudogap phase, the phase situated between insulating and superconducting phases in the cuprate phase diagram.

  • Wiring Diagram

    I am looking for a wiring diagram for GMC 2006 Sierra Seats. Heat, motors, power sources, relays etc. Anyone have this available? Black & Orange wires (2) seem to be power hook-ups, however no luck when connecting them to 12V power source. Any assist will be appreciated. Jersey Joe

  • 3 Phase Voltage

    Why is there a difference in phase to phase voltage when compared to phase to neutral? Eg: Phase to neutral = 220V Phase to Phase = maybe 440V. Why? because you double the phases? ie; 220+220=440? Then 3 phase should be 660V? 220+220+220=660V? Explain!

PERFORMANCE CONTROLS, INC.®
Sensorless Motor Drive for Harsh Environment

PERFORMANCE CONTROLS, INC. ® DHT-24 amplifier is a 3 phase motor drive that employs a proprietary Sensorless control algorithm to drive a Brushless DC motor (BLDC) that runs from a 24VDC input. However, perhaps the most important feature is that it does all this at 175C. When operating thousands of feet below ground the last thing a service provider wants is to have their drill stop because of a component failure, particularly with the high financial and reputation costs associated...
