Designed for use with any Magtrol Hysteresis,Eddy-Current or Powder Dynamometer, Magtrol In-LineTorque Transducer or auxiliary instrumentation, the DSP7000can provide complete PC control via the USB or optionalIEEE-488 or RS-232 interface. With up to 500 readings persecond, the DSP7000 is ideally suited for both the test lab andthe production line.aPPlIcatIONsIn the laboratory, the DSP7000’s high sample rate providessuperior resolution for data acquisition and curve plotting.This allows for capturing more usable motor test data duringswitching, breakdown and other transitional areas of themotor 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 aloneunit or as part of a complete PC system.MOtOr testINg sOFtwareMagtrol’s M-TEST 7 Software (sold separately) is a state-of-the-art motor testing program for Windows®-based dataacquisition. Used with the Magtrol DSP7000 Controller,Magtrol M-TEST 7 Software provides the control of anyMagtrol Dynamometer and runs test sequences in a mannerbest suited to the overall accuracy and efficiency of the MagtrolMotor Test System. The data that is generated by Magtrol’sMotor Testing Software can be stored, displayed and printedin tabular or graphic formats, and can be easily imported intoa spreadsheet.Written in LabVIEW™, M-TEST 7 has the flexibility to testa majority of motor types in a variety of ways. Because ofLabVIEW’s versatility, obtaining data from other sources (e.g.thermocouples), controlling motor power and providing audio/visual indicators is relatively easy.Magtrol’s M-TEST 7 Software is ideal for simulating loads,cycling the unit under test and motor ramping. Because it iseasy to gather data and duplicate tests, the software is idealfor use in engineering labs, production testing and incoming/outgoing inspection.DSP7001 - single channelDSP7002 - dual channel
