Torque test bench Mega Speed Dynamometer

speedperformancemulti-parameter

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 DUT 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. Device specially designed for testing dental and/or surgical handpieces as well as for testing BLDC micro-motors at very high speed at 400000rpm (and up to 1000000 rpm).
