“…A surrogate model is a type of functional relationship between input and output variables that serves as an approximation of a complex optimization objective model. In this study, the kriging surrogate model was adopted as a surrogate model, which is widely used in electric motor optimization owing to its high predictability when a non-linear input is used [25]. The kriging surrogate model is defined as follows:…”

The use of pulse width modulation (PWM) to drive permanent magnet synchronous motors (PMSM) inevitably creates current harmonics. The generated current harmonics create harmonic components of the electromagnetic force, causing noise and vibration in the PMSM and affecting the applied system. In this paper, the effect of PMSM's electromagnetic force on noise and vibration of a reciprocating compressor is analyzed. First, two PMSMs with different electromagnetic forces were designed. As the driving method, space vector PWM (SVPWM) was used, and the experimental current waveform was analyzed. Based on the Maxwell stress tensor method, the electromagnetic force of the PMSM was calculated and the noise/vibration characteristics were analyzed. Compressors were manufactured with two PMSMs with different electromagnetic forces and the noise/vibration test results were compared. The electromagnetic force of PMSM affected the noise of the compressor, especially in the domain of twice the carrier frequency, but did not affect the low-order vibrational displacement of the compressor. The finite element analysis method was used, and it was experimentally verified with the manufactured motor and compressor.INDEX TERMS Electromagnetic force density, noise and vibration, permanent magnet synchronous motor (PMSM), pulse width modulation (PWM), reciprocating compressor.

“…Compared with conventional speed motors of the same specification, high-speed motors generally have higher loss, and in order to facilitate speed regulation, variable frequency power supply is generally used, which introduces higher harmonics that will increase the loss of the motor and cause temperature rise. Especially for rotors, the added difficulty in heat dissipation leads to a significant increase in rotor eddy current loss [4][5][6] . Reference [7] conducted finite element simulation calculations on the electromagnetic losses of the high-speed motor and found that compared to sinusoidal power supply, variable frequency power supply increased the total loss of the motor by more than 45%, mainly on the rotor.…”

The operating temperature of the motor is directly influenced by motor loss, and there is a significant difference in the distribution of loss between high-speed motor and conventional speed motor, so it is extremely important to analyze the temperature field of high-speed motor. The manuscript takes a highspeed induction motor as an example for three-dimensional temperature field analysis, calculates the temperature field of the motor under various loss conditions, and obtains the characteristic relationship between different loss and winding temperature and rotor squirrel cage temperature. The rationality of the simulation model and the correctness of the analysis results are verified by comparing the motor's full load operation test with the simulation results. Finally, the basic design ideas for high-speed motors are summarized.

“…The accuracy of the surrogate model is a controversial problem, especially in the high-dimensional optimizations. As a consequence, various fitting approaches, such as response surface methodology (RSM) [27], or Kriging method [28], have recently been developed to create an approximate model with reasonable accuracy in terms of data prediction. In addition to the modern fitting approaches, the proper sampling of data can significantly reduce the potential inaccuracies in the resultant surrogate model.…”

Due to their contact-free and low-maintenance features, magnetic gears (MGs) have been increasingly investigated to amplify the torque of electric motors in electric vehicles (EVs). In order to meet the requirements of propelling EVs, it is essential to design an MG with a high torque density. In this paper, a novel flux-focusing Halbach coaxial MG (FFH-CMG) is proposed, which combines the advantages of flux focusing and Halbach permanent magnet (PM) arrays. The proposed structure has a higher torque performance and greater efficiency than conventional structures. A multi-objective design optimization based on a surrogate model is implemented to achieve the maximum volumetric torque density (VTD), torque-per-PM volume (TPMV), and efficiency, as well as the minimum torque ripple, in the proposed FFH-CMG. The employed optimization approach has a higher accuracy and is less time-consuming compared to the conventional optimization methods based on direct finite-element analysis (FEA). The performance of the proposed FFH-CMG is then investigated through 2D-FEA. According to the simulation results, the optimized FFH-CMG can achieve a VTD of 411 kNm/m3, and a TPMV of 830 kNm/m3, which are significantly larger than those of the existing MGs and make the proposed FFH-CMG very suitable for EV applications.
