“…When the actual speed increases from 0 to 4500 r/min, the experimental curves of the rotational speed, phase "a" current, and rotor displacement which are controlled by flux feedforward control in the field-weakening region are shown in Figs. [13][14][15]. Fig.…”

“…In the oriented flux vector control system of the bearingless induction motor powered by the inverter [11][12][13][14], when the BIM works below the rated speed, the motor flux can be kept constant, and its maximum output torque [15][16][17] is only limited by the rated current and the maximum current of the inverter; when the motor speed exceeds the rated speed, it enters the field-weakening region. With the increase of the counter electromotive force of the rotor winding, the output voltage of the inverter will be limited, which affects the maximum torque output of the motor.…”

In order to realize the maximum torque output (MTO) in the field-weakening region for a bearingless induction motor (BIM) stator vector control, a flux feedforward control strategy is proposed. Firstly, based on the restrictions of the stator flux oriented control and the dynamic characteristics of the current in the BIM field-weakening region, the optimal distribution of the torque current and excitation current and the dynamic model of the maximum torque output strategy are analyzed. Then, the fieldweakening region could be divided into two parts according to the change of slip. It can be proved that the BIM works under the voltage and current limitations in the field-weakening region I, and works under the voltage and torque limitations in the field-weakening region II. By this way, the optimal flux mathematical model of the BIM can be obtained. Finally, the MTO in the field-weakening region is proved. The simulation and experiment results show that the proposed flux feedforward control strategy in the field-weakening region can make the output torque and current tracking effect improve significantly when the BIM runs beyond the rated speed. At the same time, the good suspension performance of the BIM is realized.

This paper presents a practical approach to calculate the total owning cost (TOC) of a three-phase Induction Motor, which is based on the motor’s nameplate data and the purchasing price. The economic evaluation is performed considering both the induction motor electrical energy losses and its amortized annual capital cost. The proposed technique consists of three stages, where the total power losses are determined analytically in the first stage. The load loss factor (LSF) is statistically obtained to determine the total energy losses in the second stage. In the third stage, the economic evaluation was conducted. The obtained results show that the proposed approach is a helpful tool for the decision-maker when comparing the received offers from different vendors and finding the answer to the question of which offer has less TOC. Finally, the proposed method is illustrated through a numerical example and software using MATLAB was performed. Results and conclusions have been summarized and discussed.
