DSP7000 High Speed Programmable Controller

DSP7000 High Speed Programmable Controller

Product Description

Magtrol’s Model DSP7000 High-Speed Programmable. Dynamometer Controller employs state-of-the-art Digital Signal Processing Technology to provide superior motor testing capabilities. Designed for use with any Magtrol Hysteresis, Eddy-Current or Powder Brake Dynamometer, Magtrol In-Line Torque Transducer or auxiliary instrumentation, the DSP7000 can provide complete PC control via IEEE-488 or RS-232 interface. With up to 500 readings per second, the DSP7000 is ideally suited for both the test lab and the production line.


  • DSP7001 Single Channel: Low cost and easy to use
  • DSP7002 Dual Channel: Enables the support of two testing instruments with independent or tandem configurations and two fully independent control loops
  • Built-in Alarm System: For power, speed, torque, temperature, air flow, water flow, electrical overload and external inputs
  • High Speed Data Acquisition: Up to 500 torque and speed points per second of both channels with time stamp
  • High Quality, Easy-to-Read Vacuum Fluorescent Readout: Displays torque, speed, power, auxiliary and PID (proportional gain, integral and derivative) values
  • Fast Full-Curve Data Acquisition: Free-run to locked rotor in seconds
  • Speed & Torque Operating Modes: PID settings for exceptional dynamometer control
  • Programmable Digital PID Values: Controlled and stored via M-Test Software or controlled manually
  • Built-in Current-Regulated Supply: For use with Hysteresis Dynamometer or brakes up to 1amp
  • Adjustable Torque Units: English, Metric and SI are standard
  • Digital Filter: Removes undesired noise from torque signals
  • Saving: Currently used configuration can be saved and recalled at power up
  • Single or Multi-point Torque and Speed Stabilized Testing: Via M-TEST 7 Software
  • Rack Mounting: 19″ (482.6 mm) with handles
  • Backwards Compatible: Compatible with the DSP6001 (in DSP6001 mode)
  • HD5 dynamometers: Supported
  • USB: Standard
  • Low RPM: Calculation from angle (quadrature signal) and time designed to capture RPM’s as low as .001 RPM
  • Position Measurement: Two quadrature decoders

In the laboratory, the DSP7000’s high sample rate provides superior resolution for data acquisition and curve plotting. This allows for capturing more usable motor test data during switching, breakdown and other transitional areas of the motor test curve. For production and incoming inspection, the DSP7000 displays torque, speed and power at all times, allowing the Controller to be used as a manual stand alone unit or as part of a complete PC system.
