Produktbeschreibung

Magtrol’s DUAL TEST 7 is a state-of-the-art motor testing software for PC (Windows® XP sp3/7/8) based data acquisition. Used with a Magtrol Programmable Dynamometer Controller DSP7012, DUAL TEST 7 works on two channels independently with any Magtrol Dynamometer or In-Line Torque Transducer to help determine the performance characteristics of a motors under test. Up to 63 parameters are calculated and displayed utilizing DUAL TEST 7’s feature-rich testing and graphing capabilities.

An integral component of any Magtrol Motor Test System, DUAL TEST 7 performs curve tests in a manner best suited to the overall efficiency of the test rig. Written in LabVIEW™, DUAL TEST 7 has the flexibility to test a variety of motors in a multitude of configurations. The data generated from this user-friendly program can be stored, displayed and printed in tabular or graphical formats, and is easily imported into a spreadsheet.

Magtrol can also make custom modifications to the software to meet additional motor testing requirements.

Features

  • DSP7012 Programmable Controller Support
  • Full independent dual channels control software
  • Supports the optional Analog and Digital I/O Modules on the DSP7012 Programmable Controller.
  • Expanded power analyzer and power supply selections.
  • Programmable analog and digital outputs per step
  • Test speed, torque, amps, watts input, watts output and open loop parameters.
  • Capable of adjusting sampling rate and using step or ramp from one load point to the next.
  • Displays 63 Tested and Calculated Parameters: Torque, speed and auxiliary input are displayed from the DSP7012 Controller; amps, volts and watts from an (optional) power analyzer. Calculated values including horsepower, efficiency, power factor, output watts and time can also be displayed. Optional analog and digital inputs can also be displayed.
  • Three-Phase Power Analyzer Data Acquisition: Obtain data on each individual phase and/or the sum used in the chosen parameters (amps, volts, input watts and power factor).
  • Motor Shaft Direction Indicator: Indicates if the motor is turning clockwise or counterclockwise.
  • USB Interface : Computer interface USB2.0 available with DSP7012. Optional IEEE-488 or RS-232 can be added.
  • PID Adjustment Routines: Helps user adjust the system for ramp and step functions.
  • Graphing Capabilities: Display up to 5 test curves in a single graph; easy-to-read colored and labeled plots with several graph formatting options; manual or auto scaling.
  • Curve Fitting: A curve fitting routine can be applied to most motor test curves. Raw data and curve fit data can also be displayed simultaneously.
  • Save/Load Setup Function: Test procedure configurations may be stored and recalled using standard Windows® file structure

Applications

DUAL TEST 7—besides being well-suited for simulating loads, cycling the unit under test and motor ramping—is also ideal for production line, due to the full dual channels tests functions. Another time-saving feature, that engineering labs will benefit from, is the ability to duplicate tests and run them automatically. This versatile program is extremely valuable to anyone involved in motor testing.

The TCBS Thermocouple Connection Barrier Strip provides a method of connection the data acquisition device, which is usually installed in the main console, to the device being monitored up to 3 meters away. All eight thermocouples pairs are bundled into a single cable and terminated in a die cast aluminum box with barrier strip jackets for easy connection.

Interconnection errors can be avoided by using the barrier strip with the relevant thermocouple extension or compensation material. The strips are marked to identify the alloy and polarity.

The box can be supplied with optional T-nuts for easy mounting to a T-slot table or Magtrol PT 25 Base Plate.

If currents continuously reach above 20 amps, an external sensor must be used. Magtrol offers three different types of external shunts for use with Magtrol Power Analyzers. The HA Series shunt, designed for power cable hook-up utilizing 3/8-16 screws, has an insulating base and can be mounted on conductive surfaces. The LAB Series shunt also comes with an insulating base, along with thumb screws for the power leads and knurled nuts on the sensing terminals. The FL Series is a relatively small bus, bar-mounted shunt with large end blocks. The comparatively large end blocks and short spacing aid in cooling and allow the shunt to operate in more extreme environments. All shunts are calibrated on equipment with current certifications traceable to N.I.S.T.

                    [post_content] => Magtrol’s Verstellbare Motorbefestigungen der Serie AMF dienen zur sicheren Befestigung von kleinen bis mittelgroßen Motoren während eines Testdurchlaufs. Diese außerordentlich vielseitigen Befestigungsvorrichtungen ermöglichen außerdem eine einfache Zentrierung des Motors zur Verkupplung mit Hysterese-Leistungsbremsen der Serie HD. (Verkupplungen können auf Wunsch geliefert werdend.) Motoren verschiedener Länge können entweder einer befestigeten Grundplatte mit T-Nute oder einer Schieberplatte angepasst werden.

Die Befestigungen von AMF -1, -2, und -3 sind mit ein bis zwei verstellbaren Brücken ausgestattet, jede mit einer kannelierten Klemmschraube, die das Einspannen entlang der Achse des Motors ermöglicht. Die verstellbare Verbindungsbrücke an der AMF-V Befestigung enthält eine geradlinige Bewegungsklemme mit einer gummigelagerten V-Winkel-Klemmschraube, um den Befestigungsbereich zu maximieren.

Zur Absicherung des Motors bieten blockierende Fngerschrauben Schutz gegen Lagerschwingungen. Alle Verbindungsstücke zwischen dem Motor und der Befestigung sind mit Nylon gepolstert um ein kratzfreies Einspannen zu gewährleisten.

The TCBS Thermocouple Connection Barrier Strip provides a method of connection the data acquisition device, which is usually installed in the main console, to the device being monitored up to 3 meters away. All eight thermocouples pairs are bundled into a single cable and terminated in a die cast aluminum box with barrier strip jackets for easy connection.

Interconnection errors can be avoided by using the barrier strip with the relevant thermocouple extension or compensation material. The strips are marked to identify the alloy and polarity.

The box can be supplied with optional T-nuts for easy mounting to a T-slot table or Magtrol PT 25 Base Plate.
