Abstract
(EN)
Provided is a 6-line 3-phase motor that is capable of simultaneously achieving a high output and reduction of torque ripples. A 6-line 3-phase motor (100) is provided with: a stator (110) that has winding wires wound independently between phases; and a rotor (111) that has a plurality of magnets in a peripheral direction, wherein the stator (110) or the rotor (111) is configured so that a third harmonic current component in a motor current when an overmodulation voltage based on a PWM signal is applied can be greater than a third harmonic current component in a motor current when a sine-wave modulation voltage based on the PWM signal is applied.
(FR)
L'invention porte sur un moteur triphasé à 6 lignes permettant d'assurer simultanément une sortie élevée et une réduction des ondulations de couple. Un moteur triphasé à 6 lignes (100) est pourvu : d'un stator (110) qui comporte des fils d'enroulement enroulés indépendamment entre des phases ; et d'un rotor (111) qui comporte une pluralité d'aimants dans une direction périphérique, le stator (110) ou le rotor (111) étant conçu de telle sorte qu'une composante de courant de troisième harmonique dans un courant de moteur lorsqu'une tension de surmodulation basée sur un signal PWM est appliquée peut être supérieure à une composante de courant de troisième harmonique dans un courant de moteur lorsqu'une tension de modulation sinusoïdale basée sur le signal PWM est appliquée.
