“…The study utilizes MATLAB/Simulink simulations to explore the electromagnetic performance of these motors, thereby deepening insights into their distinct capabilities. While electromagnetic analysis is necessary for understanding the electrical aspects of electric motors, vibroacoustic analysis is important to ensure optimal user experience, mechanical integrity, and compliance with regulations [13], [14]. Acoustic noise and vibration reduction are among the factors that are considered in the design process of electrical machines [15].…”

The demand for electrical machines has been spurred by rising fuel costs, technological advancements, and urbanization. Consequently, there is an increased focus on developing machines with greater power density, improved efficiency, and enhanced vibroacoustic characteristics while promoting a more sustainable supply chain. This paper offers a thorough comparison of three distinct motor topologies: switched reluctance motor (SRM), interior permanent magnet synchronous motor (IPMSM), and induction motor (IM). The study begins with electromagnetic analysis of the motors, covering torque, output power, losses, and efficiency calculations. Subsequently, the investigation delves into radial force density waveforms, extracting the dominant radial force density harmonics and presenting patterns for each motor's dominant radial force harmonics. Following this, a 3D assembly of the motors is introduced for modal analysis, determining their mode shapes and natural frequencies. Finally, vibroacoustic analysis is conducted for the proposed motors, with observed differences being discussed. These analyses are conducted solely for the rated operating point, as transitioning to other operating points does not alter the pattern of radial force harmonics or the correlation between acoustic noise and radial force harmonics.INDEX TERMS Electromagnetic performance, induction motor, interior permanent magnet motor, radial force harmonics, sound pressure level, switched reluctance motor, vibroacoustic analysis.

“…Japanese scholar Morimoto proposed the average speed method [5], and successfully applied it to the permanent magnet synchronous motor drive. Scholars at Ohio State University simplified this algorithm and implemented it through software codes [6]. However, during the actual operation of the motor, external disturbances and torque fluctuations have a certain impact on the acceleration of the motor, resulting in large dynamic errors, and it is difficult to achieve a better closed-loop control of the motor speed.…”

This paper studies a method for high-precision acquisition of position signals for permanent magnet direct drive servo motors at low speed. First of all, the problem of poor position feedback accuracy and sensor feedback delay in the low-speed operation of the permanent magnet direct drive servo motor is analyzed. Secondly, through analysis and simulation, it is found that the interpolation method can play a certain role in compensating the rotor position signal. However, when the speed is close to 0, the output signal of the sensor will fluctuate in a short time, which will affect the speed control accuracy. Therefore, this paper uses the observer method to achieve high-precision acquisition of the position signal of the permanent magnet direct drive servo motor at low speed. The observer method adopts the idea of combining the system model and closed-loop control. Additionally, it makes full use of the parameter information of the motor system. The control performance of the motor can be better guaranteed through the design of the observer parameters and the accuracy of the rotor position estimation result has been greatly improved. Finally, an experimental platform for permanent magnet direct drive servo motors is built, and the rotor position signal acquisition method based on the observer method is verified to have good performance through simulation and experiments. Not only the accuracy of the rotor position estimation result is improved, but also the motor control performance is improved, realizing the stable operation of the permanent magnet direct drive servo motor at low speed.

“…In [26], available techniques for motion control, monitoring and diagnosis of PMSM using Hall-effect sensors were summarized. In [27,28], the rotor position estimation error caused by misplaced Hall sensors was analyzed, and the least square estimation method (LSM) as well as back EMF vector tracking method were compared in the steady and dynamic situations, respectively.…”

Low resolution Hall-effect sensors have been commonly applied in PMSM drives for the reason of cost and volume. Generally, rotor speed and position are estimated inaccurately due to the installation error of the sensors. The inaccurate position degrades the performance of current control and also increases torque ripples, which aggravates mechanical vibration and noise. An improved dual observer is proposed in this paper to suppress the impact of misplaced Hall-effect sensors and improve estimation accuracy. By a cascading dual Luenberger observer and combining feedback decoupling control, the low-order noises produced by the deviation of Hall signals are effectively suppressed. The effectiveness of the proposed method is verified by experimental results.
