“…Some analytical models which can estimate the flux density in the iron parts have employed in (1) to predict the core loss [119][120][121]. The estimation of the flux density based on the sizing equation and magnetic equivalent circuit of the electrical machines allows to find the core loss by (1) [122][123][124].…”

In some applications such as electric vehicles, electric motors should operate in a wide torque and speed ranges. An efficiency map is the contour plot of the maximum efficiency of an electric machine in torque-speed plane. It is used to provide an overview on the performance of an electric machine when operates in different operating points. The electric machine losses in different torque and speed operating points play a prominent role in the efficiency of the machines. In this paper, an overview about the change of various loss components in torque-speed envelope of the electric machines is rendered to show the role and significance of each loss component in a wide range of torque and speeds. The research gaps and future research subjects based on the conducted review are reported. The role and possibility of the utilization of the computational intelligence-based modeling of the losses in improvement of the loss estimation is discussed.

“…Although FEM is a powerful method, the iterative simulations make the process less suitable compared to a flexible MEC method. A flexible MEC method for a linear structure is proposed in [6], [23] for a Variable Reluctance Linear Resolver (VR-L-Resolver) and Linear Induction Machine (LIM), respectively. The flexible MEC method is applied in the mentioned works while the end-effect and the core nonlinearity are considered for a dynamic model.…”

A novel linear resolver is proposed in this paper. The excitation and signals windings are placed on the mover, and the stator structure is designed by a certain number of teeth/slots per the mover length. Therefore, the proposed structure is more simple compared to other resolver types and causes a low price structure. A flexible Magnetic Equivalent Circuit (MEC) is used for analysis thanks to its capability, introducing various structures. The resolver performance under healthy and faulty cases is evaluated, where the position error under asymmetry air-gap fault is obtained. Performed analysis shows that the proposed resolver has less than 100 µm position error. Hence it can be a proper alternative as an accurate position sensor. The simple structure and high-accurate position estimation are the advantages of the proposed resolver compared to other types. Finally, the effectiveness of the proposed resolver is validated by experimental results.

“…Force fluctuations occurring in a linear motor feed system are a topical issue that affect the accuracy of system operation. Attempts are made to solve it by applying various algorithms; from the magnetic field model of the peranent magnet air gap [13], the model of permanent magnetic linear synchronous motors (PMLSM) [14], the equivalent circuit model obtained by theoretical analysis [15,16], the conformal mapping (CM) method for determining torque [17,18], PMLSM analysis method [14], multiple changes of traction harmonics of different motion parameters [19], development of compensation control strategies to improve traction oscillations as a periodic disturbance compensation strategy [20], force wave compensation strategy [21] and a comprehensive strategy for trinities, disturbances and surges [22,23]. To maintain the dynamic stability of the linear stage and its static error at its minimum, it is required to calibrate static error by optical methods and tune the transfer function in frequency domain.…”

“…Separate studies have been performed to analyze mechanical oscillation, current circuit permeability [37], current upper limit, and control parameters in a linear motor supply system [15] but have only been defined by feedback errors without detailed analysis of traction harmonics and displacement oscillations. Such studies were performed by Yang et al [16], where the dependences between air gap fluctuations and the harmonic error is displacement fluctuation were defined.…”

Research institutions and industrial enterprises demand high accuracy and precision positioning systems to fulfil cutting edge requirements of up-to-date technological processes in the field of metrology and optical fabrication. Linear motor system design with high performance mechanical guiding system and optical encoder ensures nanometer scale precision and constant static error, which can be calibrated by optical instruments. Mechanical guiding systems has its benefits in case of control theory and its stability; unfortunately, on the other hand, there exists high influence of structure geometry and tribological effects such as friction and modal response. The aforementioned effect cannot be straightforwardly identified during the assembly process. Degradation of dynamic units can be detected only after certain operating time. Single degree of freedom systems are well investigated and the effect of degradation can be predicted, but there exists a gap in the analysis of nanometer scale multi degree of freedom dynamic systems; therefore, novel diagnostic tools need to be proposed. In this particular paper, dual axes dynamic system analysis will be presented. The main idea is to decouple standard stacked XY stage and analyse X and Y configuration as two different configurations of the same object, while imitators of corresponding axes are absolutely solid and stationary. As storage and analysis of time domain data is not efficient, main attention will be concentrated on frequency domain data, while, of course, statistical and graphical representation of dynamic response will be presented. Transfer function, dynamic response, spectral analysis of dynamic response, and modal analysis will be presented and discussed. Based on the collected data and its analysis, comparison of X and Y responses to different velocity excitation will be presented. Finally, conclusions and recommendations of novel diagnostic way will be presented.
