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).

  • 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.

                    [post_content] => Die Wirbelstrombremsen der WB-Reihe sind vielseitig einsetzbar und hervorragend geeignet für Prüfaufgaben bei hohen Drehzahlen in mittleren bis hohen Leistungsbereichen. Das Bremsmoment einer Wirbelstrombremse ist drehzahlproportional und erreicht seinen Maximalwert bei der Nenndrehzahl der Bremse. Der kleine Rotordurchmesser der Bremse garantiert ein niedriges Trägheitsmoment. Die Bremse wird wassergekühlt, wobei das Wasser durch den Stator geleitet wird. Dank dieser Kühlung eignen sich die WB-Bremsen für hohe Dauerbelastungen (max. 140 kW). Wirbelstrombremsen der WB Reihe verfügen über eine Genauigkeit von ± 0.3 % bis ± 0.5 % vom Skalenendwert, abhängig vom Typ und dessen Konfiguration.

Funktionsprinzip der Wirbelstrombremsen

Die WB Reihe Wirbelstrom entwickeln ihre volle Leistung bei hohen Drehzahlen. Die WB Reihe ist besonders für Motoren vorgesehen, die mit hohen Drehzahlen bis 80 000 min-1 (bis 100 000 min-1 mit WB 23 / 27; siehe spezifisches Datenblatt) rotieren. Das Bremsmoment ist von der Drehzahl abhängig.

Optischer drehzahlaufnehmer
Jede Leistungsbremse der WB Series hat einen optischen Drehzahlsensor, der standardmäßig geliefert wird. Die WB 32 hat einen optischen Drehzahlsensor mit 4 PPR (Impulse pro Umdrehung) , WB 43 und WB 65 HS haben einen Drehzahlsensor mit 30 PPR ; die WB 65, WB 115 & WB 15 haben einen optischen Drehzahlsensor mit 60 PPR.

PT Series T-slot Base Plates are used for creating a basic test rig by mounting a Magtrol Dynamometer and/or Torque Transducer in line with the unit to be tested. Its solid, warp-resistant structure and multiple, single-sided T-slots enable modular construction that is cost-effective and easy to assemble.

Magtrol’s EMA Series Stand Alone Encoder provides a squarewave output on two channels for up/down counting or free-runmotor speed measurement applications. Each channel outputs the specified pulses per revolution of the encoder shaft, and is 90° phase-shifted in order to determine direction when used with the appropriate counter/timer DAQ board. The device incorporates an infrared optical switch and disk assembled into a rugged aluminum housing. The encoder is supplied with an 8 mm rectangular key for easy alignment to a Magtrol PT 25 Base Plate.

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.

            [post_content] => Die Wirbelstrombremsen der WB-Reihe sind vielseitig einsetzbar und hervorragend geeignet für Prüfaufgaben bei hohen Drehzahlen in mittleren bis hohen Leistungsbereichen. Das Bremsmoment einer Wirbelstrombremse ist drehzahlproportional und erreicht seinen Maximalwert bei der Nenndrehzahl der Bremse. Der kleine Rotordurchmesser der Bremse garantiert ein niedriges Trägheitsmoment. Die Bremse wird wassergekühlt, wobei das Wasser durch den Stator geleitet wird. Dank dieser Kühlung eignen sich die WB-Bremsen für hohe Dauerbelastungen (max. 140 kW). Wirbelstrombremsen der WB Reihe verfügen über eine Genauigkeit von ± 0.3 % bis ± 0.5 % vom Skalenendwert, abhängig vom Typ und dessen Konfiguration.

Funktionsprinzip der Wirbelstrombremsen

Die WB Reihe Wirbelstrom entwickeln ihre volle Leistung bei hohen Drehzahlen. Die WB Reihe ist besonders für Motoren vorgesehen, die mit hohen Drehzahlen bis 80 000 min-1 (bis 100 000 min-1 mit WB 23 / 27; siehe spezifisches Datenblatt) rotieren. Das Bremsmoment ist von der Drehzahl abhängig.

Optischer drehzahlaufnehmer
Jede Leistungsbremse der WB Series hat einen optischen Drehzahlsensor, der standardmäßig geliefert wird. Die WB 32 hat einen optischen Drehzahlsensor mit 4 PPR (Impulse pro Umdrehung) , WB 43 und WB 65 HS haben einen Drehzahlsensor mit 30 PPR ; die WB 65, WB 115 & WB 15 haben einen optischen Drehzahlsensor mit 60 PPR.
