All imc electric motor test stands are configured for continuous operation. However, because purely continuous operation often places high demands on test stand structure and design, imc also offers tailored test stands, specifically designed for endurance testing. These, for instance, perform a few test tasks only, that however run over a period of weeks or months. In order to maintain test efficiency, two, three or six load machine assemblies operate in parallel, whereby operation in a temperature or climate chamber is also possible. The actual test procedure is established in close coordination with the customer including the desired reactions upon possible test object failures or with early detection of drift in characteristic values.
