In the company Domel, a large part of the production is intended for commutators.
Therefore, it is important to perform as many different tests as possible in order to find
possible faults that would jeopardize the operation of commutator in the electric motor. One
of the problems is the scattering of the slats. This can occur at high rotational and temperature
loads. The company already has a testing device with a steel rod, which transmits revolutions
and torque from the electric motor to the tester. We have quite a few problems with it, as it
breaks very often, even with the slightest vibration. The thesis presents the design and
manufacture of testing devices with a magnetic clutch, which protects the electric motor in
the event of sudden changes in torque, and at the same time it is a much more convenient for
the assembly and disassembly of testers from the devices. The final part presents the results
of testing, findings and suggestions for further work.
