Measuring and Testing of Electric Motors, Modelling

Being an independent authority the IMS performs measurements and tests of electrical drives. Or laboratory provides several test stands of different power classes as well as a number of modern, high-quality measuring instruments.

For example the degree of efficiency of an asynchronous motor can be determined it can be categorized into efficiency classes according to IEC 60034-30.This is going to become more and more important due to the directive for ecological design. Inverters with currents up to 32 A are available. Measurements are conducted with power analysers and torque shafts up to 100 Nm and 100’000 rpm. In addition to the metrological determination of motor parameters evaluations, calculations and modelling are performed for the identification of potentials to increase efficiency of the whole mechatronical system.
