Description

好ましくは、トルクコンバータ本体は、フロントカバーとタービンとの間に配置されるロックアップ装置をさらに有する。タービン、及びロックアップ装置の少なくともいずれかは、非磁性体によって形成される。
Preferably, the torque converter body further includes a lockup device disposed between the front cover and the turbine. Turbine, and at least one of the lock-up device is formed by a non-magnetic material.

まず、動力伝達装置制御部１１４は、動作指令入力部１１５からエンジンの始動指令を取得すると、エンジン始動モードと判定して、回転電機３をスタータとして始動機能を発揮させる。詳細には、動力伝達装置制御部１１４は、エンジンの始動指令に基づき、インバータ１１２を駆動して固定子３１に三相交流電流を流すとともに、電流制御部１１１を駆動制御して界磁コイル３３に電流を流す。界磁コイル３３に電流が流れると、回転子３２の第１爪極３２ａと第２爪極３２ｂとが励磁される。この結果、回転子３２が固定子３１に対して回転を開始するとともに、固定子３１において誘起電圧を有する起電力が発生する。この一連動作は一例であり、逆の順でも動作させることができる。 First, when the power transmission device control unit 114 obtains an engine start command from the operation command input unit 115, the power transmission device control unit 114 determines that the engine start mode is set, and causes the rotating electrical machine 3 to function as a starter. Specifically, the power transmission device control unit 114 drives the inverter 112 to flow a three-phase alternating current through the stator 31 based on the engine start command, and drives and controls the current control unit 111 to control the field coil 33. Current is passed through. When a current flows through the field coil 33, a first Tsumekyoku 32 a and the second Tsumekyoku 32b of the rotor 32 is energized. As a result, the rotor 32 starts rotating with respect to the stator 31 and an electromotive force having an induced voltage is generated in the stator 31. This series of operations is an example, and the operations can be performed in the reverse order.
