DDC Introduces PW-8X075: The First of the New Magnum Motor Drive Series™

Data Device Corporation,  Bohemia, New York, announces the introduction of its New Magnum Motor Drive Series™ the Magnum 75: PW-8X075, Universal Modular Motor Drive. The Magnum Series Drives consist of three unique half-bridge drives rated at 600 volts and 75 amps that can drive brushless dc, induction and brush motors.

The first drive in the series is the "basic" Magnum 75, which contains an isolated power supply, a pair of gate drivers, and IGBT power stage with flyback diodes. The IGBTs are individually protected from shorts applied to the output. The input or command side of the isolation barrier has the switch control, fault status, and power down control. The input side only requires a single 5 volts supply to operate.

The second drive is the "current sense" Magnum 75, which contains all the elements of the basic drive plus an isolated current sense circuit. The current sense resistor is isolated from the sense amp, which provides a unipolar (0-5 volt), microprocessor compatible, current signal.

The third drive is the "regen" Magnum 75 that also contains all the elements of the basic drive plus an isolated regenerative clamp circuit that monitors the high voltage bus. The adjustable bus monitor trips an IGBT that clamps the bus when motors are back-driven and operating in the generator mode. The clamp prevents bus "pump-up" and possible damage to the drive.

All these drives can be used in any combination depending on the particular application. The high reliability and flexibility of these drives make them particularly suitable for aerospace and military applications, including:

  • Actuator systems for primary and secondary flight controls, thrust reverser, and landing gear on aircraft
  • Pump motors for fuel and hydraulic fluid
  • Fan and compressor motors for environmental conditioning
  • Thrust vector position control of missiles, drones, and RPVs
  • Antenna and radar positioning
Data Device Corporation is an international leader in high-reliability data conversion interface components and subsystems for military and commercial applications. Established in 1964 with the introduction of the first synchro-to-digital module, DDC's design and manufacturing facility is located in Bohemia, New York.
