The transmitted power of motors can be defined by test bench examinations, in which the motor needs to be dismounted. By applying diagnostic methods only minimal disassembly, or indeed none at all, is necessary. In this paper diagnostic methods are systematized by different studies. Moreover, a new diagnostic procedure (established by the authors) is also introduced, which can be carried out by a relatively cheap measuring system design.

Power measurement on a roller test bench is a well-tried technique for vehicle examination. Basically, the wheel parameters (tractive force, torque, power) are measured, but there are also procedures for motor power measurement. By applying the new procedure, the diagnostic method, (simple construction and test bench construction at a favourable price) torque and power characteristics of the mounted motor can be defined. The theoretical considerations of the new measuring technique and the implementation of the measuring system are introduced in this paper.

Test bench for drive motor power and torque curve determination.

In this study the diagnostical measuring systems and, for the first time, the measuring principle and technology of the new theory-based roller power test bench are presented. For its construction measurements have been carried out which make an important contribution to the research.

The results of the research contribute to the development of diagnostics methods and to making them more wide-spread.
