“…The waveform of the airgap flux density around the periphery, induced voltage, magnetic flux linkage, inductances, developed electromagnetic torque and torque ripple are possible to investigate by means of FEM. The magnetic flux distribution for rated current in d and q axis in the new optimized cageless barriers rotor was reported in Reference [1].…”

“…The orange curve depicts the simulated torque production of the motor in static condition. This is due to the nature of the FEM analysis used in Reference [1], where the stator was fed with current equivalent to the desired AC current and the rotor was positioned in an angle matching the load angle, but in a non-rotating state. Thus, there was no damping caused by rotation and moment of inertia.…”

“…In many industrial or other applications where electrical machines are used, strong emphasis is placed on lower energy consumption. This can be achieved by new materials, new design topologies, optimization or energy saving control strategies, if the electrical machine is used as a drive with converter [1,2]. The most common electrical machines used in the industry are squirrel cage induction motors (IM) because of their low costs, robustness and maintenance.…”

“…During design process, the main idea is to maximize the ratio between synchronous inductances in direct axis L d and in quadrature axis L q . This feature is very important from the point of view of developed reluctance electromagnetic torque [1]. On the other hand, the high inductance ratio L d /L q leads to possible instability of RSM which works with DOL.…”

In this paper the effect of saturation on torque production of a reluctance synchronous motor (RSM), which was originally built as an induction motor (IM), is investigated. The rotor was replaced with new one, designed as synchronous reluctance cageless rotor with barriers, the shape and number of which were optimized to maximize the reluctance ratio. The torque measurement was done while the RSM was fed by frequency converter controlled by a microcontroller with closed loop field oriented control strategy to find out how saturation effects the developed torque at various values of the currents and speeds. It is shown how the load angle at which the maximum torque was achieved is changed. It was found out that the load angle was shifted to higher values depending on the speed of operation.
