Title (EN) IN-WHEEL MOTOR SYSTEM AND ELECTRIC AUTOMOBILE
(FR) SYSTÈME DE MOTEUR-ROUE ET AUTOMOBILE ÉLECTRIQUE
(JA) インホイールモータシステムおよび電気自動車
Abstract:
(EN) Provided is an in-wheel motor system with which the amount of wiring between an in-wheel motor drive device and an inverter device can be reduced, and a situation in which the in-wheel motor drive device is large and thus difficult to be put into the wheel can be eliminated. In a system in which an in-wheel motor drive device (10) and an inverter device (1) mounted on a vehicle body are connected by wiring, the following are installed in the in-wheel motor drive device (10): an RD converter (2) that converts a detection signal of a resolver (6), which detects the rotation of a motor, to a digital signal; a temperature sensor circuit (18) that processes a detection signal of a motor temperature sensor (11); and a communication circuit (22). A superposing means (28) that superposes a signal on the power source current may be provided.
(FR) L'invention concerne un système de moteur-roue avec lequel la quantité de câblage entre un dispositif d'entraînement de moteur-roue et un dispositif onduleur peut être réduite, et une situation, dans laquelle le dispositif d'entraînement de moteur-roue est de grande taille, et donc difficile à placer dans la roue, qui peut être éliminée. Dans un système dans lequel un dispositif d'entraînement de moteur-roue (10) et un dispositif onduleur (1) montés sur un corps de véhicule sont connectés par câblage, les éléments suivants sont installés dans le dispositif d'entraînement de moteur-roue (10) : un convertisseur RD (2) qui convertit un signal de détection d'un résolveur (6), qui détecte la rotation d'un moteur, en un signal numérique; un circuit de capteur de température (18) qui traite un signal de détection d'un capteur de température de moteur (11); et un circuit de communication (22). Un moyen de superposition (28) qui superpose un signal sur le courant de source d'alimentation peut être fourni.
(JA) インホイールモータ駆動装置とインバータ装置間の配線が少なくて済み、またインホイールモータ駆動装置が大きいためにホイールに入り難くなることのないインホイールモータシステムを提供する。インホイールモータ駆動装置(10)と、車体上に設置されたインバータ装置(1)とが配線により接続されたシステムにおいて、次の構成とする。モータの回転を検出するレゾルバ(6)の検出信号をデジタル信号に変換するRDコンバータ(2)、モータ温度センサ(11)の検出信号を処理する温度センサ回路(18)、および通信回路(22)をインホイールモータ駆動装置(10)に搭載する。電源電流に信号を重畳させる重畳手段(28)を設けてもよい。
