The Investigations of Dynamic Characteristics of a Stepper Motor

The aim of the work is the examination of dynamic characteristics of a stepper motor. The results of the investigations will be applied to assess the usability of the stepper motor as a generator of the periodically variable motion of actuators. The examples of mechanical generators of periodically variable motion are gear, chain and cogbelt transmissions. The complex unevenness of the work can be achieved by the application of properly designed and manufactured gear wheels. The investigations have been performed with the application of versatile test stand which consisted of a set of shafts with torque sensors. The loads have been applied by a magnetorheological brake.
