EM-TEST 1.0 Endurance Motor Testing Software

Magtrol’s new EM-TEST 1.0 is an endurance motor
testing Program for PC (Windows®XP/VISTA) based data
acquisition. Combined with a Magtrol DSP6001 High
Speed Programmable Controller, EM-TEST 1.0 works with
any Magtrol dynamometer or in-line torque transducer to
determine the performance characteristics of a motor under
test. Up to 30 parameters are calculated and displayed utilizing
EM-TEST 1.0’s unique testing and graphing capabilities.

An integral component of any Magtrol Endurance Motor Test
System, EM-TEST 1.0 performs curve testing in a manner
best suited to the overall efficiency of the test rig. Written in
LabVIEW™, EM-TEST 1.0 has the flexibility to test a variety
of motors in a multitude of configurations. The data generated
EM-TEST 1.0 Configuration Test
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.

Applications

EM-TEST 1.0 is designed for long-term motor test cycling. It is ideal for developmental applications. It has the ability to duplicate tests and run them automatically. This versatile program is extremely valuable to anyone involved in motor testing. EM-TEST 1.0 can be used as stand alone software or in combination with M-TEST 5.0 Motor Testing Software.

SpecificFeatures

• Global Project: Manages Data and Setup of the current project.
• Automatic GPIB and DAQmx Device/Address Detection:
  Displayed within program to easily check communication
  parameters.
• Lock / Unlock function: Front Panel lock function prevents
  modification by an unauthorized operator.
• Set-point table: The set-point curve is defined in the data table. Sampling rate, voltage and relay state are also defined in this table.
• Endurance Testing: Tests speed, torque, amps, watts input, watts output and open loop parameters. Capable of adjusting sampling rate by step and using step or ramp from one load point to the next.
• Relay Control: Up to 6 customized relay controls
• Temperature Measurement: Up to 8 thermocouple channels are included in the standard program.
• Temperature Security: Over-Temperature control and Hysteresis Temperature function.
• Three-Phase Power Meter Data Acquisition: Obtain data on
  each individual phase and/or the sum used in the chosen parameters (amps, volts, input watts and power factor).
• Spanning file function: Auto-Incrementation of filename
  depending on cycle, hours, days or file size.
• Graph and display during test: Displays previous files during test in tabular or graphic view.
• Recovery Function: Recovers test if the computer crashes
  (Windows® problem, power off).

Standard Features

• IEEE-488: Computer interface with National Instruments™ PCI-GPIB .
• Multiple Language Support: Switch to/from English, French, German at any point during the program. Additional language dictionaries can be created/edited by the user.
• Automatic Load Defaults Option: Downloads testing instrument parameters based on model number.PID Adjustment Routines: Helps adjust the system for step functions.
• Rapid Graph Plotting: Change both the X- and Y-axis to display additional test curves, without having to exit the graph.
• Displays 30 Tested and Calculated Parameters: Torque, speed and auxiliary input are displayed from the DSP6001. Amps, volts and watts are displayed from a (optional) power analyzer. Calculated values including horsepower, efficiency, power factor, output watts, cycle and time can also be displayed.
• 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.
• Context Help: Hover over any field or parameter with the mouse to display a context help box.

Temperature Sensor Measurement

Up to 4 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 1.0, 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.
