Product Description

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] => DES 410 Series Power Supplies are specially designed for the full range of Magtrol’s Eddy-current and Powder brake dynamometers with the design goal providing the best response time. The DES 410 Series supplies are packaged in an industrial housing made of cast aluminum. This offers superior protection against radiated emissions in order to avoid any disruption of the surrounding electronics modules. This housing must be installed directly on the test bench, next to the brake, as close as possible.

The DES 410 Series supplies can be controlled by digital signals and analog set point coming from peripheral electronics. The DSP7010 Dynamometer Controller has been designed to work with the DES Series.

Control

The Power supply can be switched ON by remote control. The STAND-BY signal enables the output current to be delivered. This excitation current is controlled by a set-point in the 0-10 V DC range. The nominal value of the excitation current is set by internal resistors. There are two discrete outputs for alarms (open collector). The first is the "Temperature Alarm". It will indicate if the cooling water of the Dynamometer or the inner temperature of the DES 410 Series are out of limits. The second is the "Electrical Alarm". It occurs when an over current or a short circuit is detected. The output current is immediately turned OFF and latched while the General Alarm Relay is set under its Alarm position. A low state for 200 ms of the Stand-by signal resets the latch.

For applications with TANDEM dynanometers, the DES 410 Series units also control the power supply of the electromagnetic clutch.

Supply Voltage

The main supply voltage of the DES Series is in the 115/230 VAC - 50/60 Hz range. No selection is required.

The DES 410 power supply features a galvanic insulation between the main circuit and the dynamometer power.

The DES 411 does not have galvanic separation. For safety reasons, the DES 410 Series case has to be grounded and the use of a ground fault current circuit breaker is recommended.

Analog Input Measurement

Up to 128 thermocouples or 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. M-TEST 7, with its complete dynamometer control, even allows for analog measurement while performing load simulation for duty cycle and life testing.

Applications

M-TEST 7—besides being well-suited for simulating loads, cycling the unit under test and motor ramping—is also ideal for production line and inspection applications, due to its pass/fail test function. 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] => Magtrol offers these calibration beam assemblies and weights for calibrating HD-Series Hysteresis Dynamometers. To perform a successful dynamometer calibration, precision weights heavy enough to apply a torque at or close to the full scale rating are required. Magtrol WT Series Calibration Weights are equal to the dynamometer's torque value, divided by the distance between the outer pin and centerline of the corresponding CB Series Calibration Beam. Calibration Weights are available in English or SI units. Calibration Beams are marked for both English and SI weights. For detailed dimension drawings, click on the model's underlined link. A PDF document will open in a new window.(Adobe Acrobat Reader 7.0, or later, is required.)
