MAGTROL - Motor Testing & Sensors

MSD Mega Speed Dynamometer is the latest Magtrol innovation in the very high-speed motor and system testing. Challenged by its numerous customers in the Dental and Surgical field, Magtrol is pushing the limit to a level which was never reached. 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 20 mN·m Reaction Torque Sensor having a resolution of 0.01 mN·m. 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 and the inertia is very low (no friction, no residual or drag torque).... more info: www.magtrol.com
