要約(英語): In recent years, progress in power semiconductor switching devices has created more additional advantages that can be realized using multi-phase inverter-fed motors. The authors propose a MATRIX motor to realize electric motors with higher functionalities than conventional electric motors. Since the MATRIX motor is driven by H-bride inverters connected with each phase winding, it has a high degree of freedom in control. Moreover, these inverters can change their connections to different phase coils to realize a wide operating range. The voltage equation of each mode can be expressed using the transformation matrix when the winding connection is changed. Therefore, we call the proposed motor MATRIX motor. In addition, since motors are being applied to various applications that operate within proximity of people, further quietness of the motor is required. In this paper, we propose a method to suppress vibration caused by a specific harmonic order radial direction electromagnetic force via teeth flux density control using the MATRIX motor. The specific order radial force and vibration are suppressed by utilizing two features of the MATRIX motor. One is a high degree of freedom of current control owing to multi-phase drive and the other is local flux density observation. The effectiveness of the proposed method was clarified using experimental results.
