MSD Mega Speed Dynamometer

Support & Downloads

Product Description

The MSD – Mega Speed Dynamometer was developed for testing very high speed motors such as BLDC, dental turbine and surgical tools. The braking affect is based on an Eddy Current induced aluminum disc directly mounted on the MUT (Motor Under Test) shaft. Torque is measured frictionless by a Reaction Torque Sensor mounted under the test bench surface. Due to the thermal effect on the disc, the Mega Speed Dynamometer is not suitable for endurance testing, but can be utilized to generate a fast curve or perform point to point testing. An infrared sensor monitors the temperature of the disc and can stop the test in case of overheating. The disc can be designed and sized according to the motor parameters. The system is contactless therefore alignment is not critical.  Due to this, the system has very low inertia and therefore no residual or drag torque thus having less influence on testing parameters. The speed limitation is based on the Motor Under Test and its ability to drive the disc. Systems reaching speeds of 320 000 rpm have already been manufactured.

M-Test LabVIEWTM based software controls the system and captures the test data. It allows the programing set up of a dedicated test profile. Every Mega Speed Dynamometer will be designed around motor characteristics and performances to match the best possible test results.   Specific motor fixture may need to be designed to suit each motor form and dimension.

The Mega Speed Dynamometer (MSD Series) enhances Magtrol’s expertise in high-speed applications and ideally complements 1 WB 23 and 1 WB 27 Dynamometers enabling motor testing up to 100 000 rpm

                    [post_content] => Magtrol’s SBB 14 Signal Breakout Box is designed to assist in the monitoring of speed, torque and index signals obtained from either a Magtrol dynamometer or torque transducer. The easy-to-use SBB 14 is simply inserted in series between a Magtrol controller and any Magtrol dynamometer or torque transducer. Connections are made via 14-pin signal cables.

Speed, torque and index signals are then outputted through BNC connectors to an oscilloscope or other DAQ instrumentation device. A toggle switch is now provided to allow switching between a torque transducer and an external encoder wired to the encoder input. The SBB 14 Signal Breakout Box is a convenient and reliable accessory that reduces the necessary wiring required for signal monitoring.

                    [post_content] => Magtrol's M-TEST 7 is a state-of-the-art motor testing program for PC (Windows® 7 SP1) based data acquisition. Used with a Magtrol Programmable Dynamometer Controller, M-TEST 7 works with any Magtrol Dynamometer or In-Line Torque Transducer to help determine the performance characteristics of a motor under test. Up to 63 parameters are calculated and displayed utilizing M-TEST 7's feature-rich testing and graphing capabilities.

National Instruments LabVIEW an integral component of any Magtrol Motor Test System, M-TEST 7 performs ramp, curve, manual, pass/fail, coast, temperature, locked rotor temperature and running heating temperature tests in a manner best suited to the overall efficiency of the test rig. Written in LabVIEW™, M-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.

NOTE: M-TEST 7 does not support the following:
  • 5240, 4629B or older controllers
  • 4612B, 4614B or older power analyzers
  • National Instruments FieldPoint analog I/O
  • Advantech PCL-725, PCI-1760 digital I/O
**MTEST-7 Motor Test Software is offered as a single seat license. Additional seats can be purchased and added to the original license. Contact sales for pricing.** [table id=21 /]

License Verification via Crypkey Casper E-Register

Casper eRegister provides automatic authorization of M-TEST 7 using serial numbers. With this solution, the customer pre-pays the license fee and is then provided with a serial number to automatically obtain a code to unlock M-TEST 7 via the Internet. Casper eRegister works 24/7/365, without human intervention. Just click on the electronic registration button on the M-TEST 7 license configuration screen.

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.

System Minimum Requirements

  • Personal computer with Intel® Pentium® IV processor (or equivalent)
  • Microsoft® Windows® 7 SP1
  • 2 GB RAM
  • 1 GB of available hard drive space
  • VGA color monitor with minimum screen resolution of 1024 × 768
  • National Instruments™ PCI-GPIB card, GPIB-USB-HS Interface(available from Magtrol)
  • RS-232 serial interface can be used, instead of GPIB card, for interfacing with Magtrol DSP6000, DSP6001 or DSP7000 Controllers. In addition, a USB Interface can be used with the DSP7000 Controller.
