Remote experiments: Step motor control and magnetic field visualization of induction machine

The paper presents two new remote experiments developed in the Laboratory of electric machines drives and regulation within the Faculty of Technical Sciences in Cacak, Serbia The first experiment presents the control and monitoring of eight-pole, three-phase step motor with permanent magnets. The experiment is remotely controlled by selecting the speed and direction of rotation. In the second experiment, magnetic field (pulsation, elliptical and rotating) created by two-pole, three-phase induction motor is observed and measured. Both experiments are controlled remotely by real-time video streaming, enabled by the set of video cameras.
