Description du produit

Magtrol’s EM-TEST is an Endurance Motor Testing Software for PC (Windows 7 SP1 / 10) based data acquisition. Combined with a Magtrol DSP 7000 Series High Speed Programmable Controller, EM-TEST works with any Magtrol dynamometer or in-line torque transducer to determine the performance characteristics of a motor under test. Up to 128 parameters are calculated and displayed utilizing EM-TEST’s unique testing and graphing capabilities.

An integral component of any Magtrol Endurance Motor Test System, EM-TEST performs curve testing in a manner best suited to the overall efficiency of the test rig. Written in LabVIEW™, EM-TEST 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.

Analog Input Measurement

Up to 128 Analog Sensors can be read and monitored during a motor test. Heat rise curves on the bearings, windings and housing of a motor can be performed and air flow/exhaust efficiencies can be measured with an air tool or internal combustion engine.

EM-TEST, with its complete dynamometer control, even allows for analog measurement while performing load simulation for duty cycle and life testing.

CAUTION: Specific hardware (e.g. NI™ 9211,…) is required to enable this function.

Temperature Sensor Measurement

Up to 128 thermocouples can be read and monitored during a motor test. Heat rise curves on the bearings, windings and housing of a motor can be performed. EM-TEST, with its complete dynamometer control, allows for sensor measurement while performing load simulation for duty cycle and life testing.

Hysteresis function: If the temperature exceeds the high threshold, the test passes to PAUSE mode and a relay is disabled. When the temperature passes under the low threshold, the test passes to RUN mode and a relay is enabled.

CAUTION: Specific hardware (e.g. NI™ 9211,…) is required to enable this function.

Relay Control

Up to 12 relays can be controlled during test. The state of each relay can be set for each step.

CAUTION: Specific hardware (e.g. NI™ 9482,…) is required to enable this function.

                    [post_content] => Les alimentations DES Série ont été conçues pour être utilisées avec toute la gamme de freins à courant de Foucault (WB Série) et à poudre (PB Série) de Magtrol en garantissant des temps de réponse les plus courts. Afin d’éviter toute perturbation sur les modules électroniques environnants, les alimentations DES Série sont montées dans un boîtier industriel en fonte d’aluminium injecté. Ce boîtier doit être fixé directement sur le banc d’essai, le plus près possible du frein.

Les alimentations DES Série peuvent être contrôlées par des consignes analogiques et digitales provenant d’une électronique périphérique, idéalement un contrôleur programmable DSP 7010 qui a été spécialement développé pour les fonctionner avec les alimentations DES Série.

Contrôle

Les unités d’excitation peuvent être mises sous tension par l’intermédiaire d’une commande à distance. Une commande STAND-BY permet d’activer l’excitation du frein. Le courant d’excitation est contrôlé par une consigne 0-10 V DC. La valeur nominale du courant d’excitation est ajustable par des résistances internes.

Deux sorties discrètes sont disponibles pour des alarmes (collecteur ouvert). La première sortie sert d’alarme de température et indique un éventuel dépassement de la température de l’eau de refroidissement du frein dynamométrique ou de la température interne de l’alimentation DES Série. La deuxième sortie «Alarme électrique» indique si une surintensité de courant ou un court-circuit ont été détectés. Le courant de sortie est immédiatement coupé (OFF) et le restera, le relais d’alarme général étant placé en position d’alarme. Un état «bas» du signal STAND-BY de 200 ms annule l’alarme.

Lors d'une utilisation avec les freins TANDEM, les alimentations de la série DES contrôlent également l'alimentation de l'embrayage électromagnétique.

Tension d’alimentation

La tension d’alimentation des DES Série doit se trouver dans la plage de 115 / 230 V AC - 50 / 60 Hz. Aucune sélection ne doit être opérée. L'alimentation DES 410 comprend une séparation galvanique entre le circuit d’alimentation et l’excitation du frein dynamométrique.

L'alimentation DES 411 ne dispose pas de séparation galvanique. Pour des raisons touchant à la sécurité, elle doit être mise à terre et un disjoncteur à courant de défaut est recommandé.

            [post_content] => Les alimentations DES Série ont été conçues pour être utilisées avec toute la gamme de freins à courant de Foucault (WB Série) et à poudre (PB Série) de Magtrol en garantissant des temps de réponse les plus courts. Afin d’éviter toute perturbation sur les modules électroniques environnants, les alimentations DES Série sont montées dans un boîtier industriel en fonte d’aluminium injecté. Ce boîtier doit être fixé directement sur le banc d’essai, le plus près possible du frein.

Les alimentations DES Série peuvent être contrôlées par des consignes analogiques et digitales provenant d’une électronique périphérique, idéalement un contrôleur programmable DSP 7010 qui a été spécialement développé pour les fonctionner avec les alimentations DES Série.

Contrôle

Les unités d’excitation peuvent être mises sous tension par l’intermédiaire d’une commande à distance. Une commande STAND-BY permet d’activer l’excitation du frein. Le courant d’excitation est contrôlé par une consigne 0-10 V DC. La valeur nominale du courant d’excitation est ajustable par des résistances internes.

Deux sorties discrètes sont disponibles pour des alarmes (collecteur ouvert). La première sortie sert d’alarme de température et indique un éventuel dépassement de la température de l’eau de refroidissement du frein dynamométrique ou de la température interne de l’alimentation DES Série. La deuxième sortie «Alarme électrique» indique si une surintensité de courant ou un court-circuit ont été détectés. Le courant de sortie est immédiatement coupé (OFF) et le restera, le relais d’alarme général étant placé en position d’alarme. Un état «bas» du signal STAND-BY de 200 ms annule l’alarme.

Lors d'une utilisation avec les freins TANDEM, les alimentations de la série DES contrôlent également l'alimentation de l'embrayage électromagnétique.

Tension d’alimentation

La tension d’alimentation des DES Série doit se trouver dans la plage de 115 / 230 V AC - 50 / 60 Hz. Aucune sélection ne doit être opérée. L'alimentation DES 410 comprend une séparation galvanique entre le circuit d’alimentation et l’excitation du frein dynamométrique.

L'alimentation DES 411 ne dispose pas de séparation galvanique. Pour des raisons touchant à la sécurité, elle doit être mise à terre et un disjoncteur à courant de défaut est recommandé.
