High reliability smart power 3-phase motor drive

Design and manufacturer of high-reliability connectivity, power and control solutions, Data Device Corporation (DDC), has introduced a new high power 3-Phase Bridge drive designed to precisely deliver current to windings of 3-Phase Brush and Brushless DC Motors, with a high-efficiency MOSFET drive stage. The new PWR-82335 motor drive offers up to an eight times improvement in power efficiency compared with the previous generation PWR-82331 bridge drive, and is a pin compatible direct replacement.

The new rugged, compact 3-phase motor drive hybrid (PWR-82335) utilises a high-efficiency MOSFET drive stage with 200 VDC rating, to deliver a high-speed switching frequency of up to 50kHz and a high current capability of up to 30A to the motor. Featuring an extended -55 to 125°C temperature range, with available military processing options, the PWR-82335 is suitable for harsh, space constrained defense and aerospace environments.

Key features:

  • Suitable for harsh defense and aerospace environments, being able to endure extreme:
    • Shock and vibration
    • Temperature (-55 to 125°C)
  • Provides constant output performance for switching frequencies from DC to 50kHz
  • Powerful MOFSET drive stage enables:
    • High speed switching frequency up to 50kHz
    • High current, up to 30A
    • High efficiency, up to an eight times improvement over earlier generation PWR-82331 motor drive
  • Pin compatible direct replacement for PWR-82331 hybrid motor drive

“Packaged in a small, ruggedised case, with a high-efficiency MOSFET drive stage, this high-reliability motor drive is an excellent choice for harsh, space constrained defense and aerospace environments requiring optimised performance,” stated Michael Agic, DDC Product Line Manager, Motor Controllers.
