Abstract :
The paper describes a novel dynamometer without any rotating parts which could possibly best be described as a machineless or electronic dynamometer. The dynamometer enables testing of induction motors to be carried out without the need to connect a load to the machine´s drive shaft. Full load temperature rise tests are achieved by using a novel method of synthetic loading which uses microprocessor controlled power electronics to generate the two distinct supply frequencies of the existing dual frequency synthetic loading method
