The MSD - Mega Speed Dynamometer was developed for the testing of very high speed motors such as BLDC, Dental Handpieces, Air Turbines and Surgical Tools. The braking effect is based on Eddy-Current induced on an aluminum disc directly mounted on the DUT (Device 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 used to generate a fast curve or perform point to point testing. An infrared sensor monitors the temperature of the disc and stops 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 over 380000rpm have already been manufactured.
MSD-TEST Software is developed in a LabVIEW™ environment. It 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 adapted around the motor characteristics and performances to match the best possible test results. Specific motor fixtures will be designed to suit each motor form and dimensions. Motor fixtures are available for fixturing handpiece or motor.
Air pressure sensor(s) can be provided as an option. The systems offers 2 analog ±10VDC outputs as well as 6 analog ±10VDC inputs (which can be configured for speed, torque, pressure,...) Included calibration weights and arms allow to conduct periodical calibration process supported by a dedicated software routine.
The Mega Speed Dynamometer (MSD System) enhances Magtrol's expertise in high-speed applications and ideally complements of WB23 & WB27 Dynamometers enabling motor testing up to 100 000 rpm, with nominal torque of 80mN·m, respectively 150mN·m.
