アプリケーションにかかわらず、低電圧液体ポンプやシャーシ & セーフティ用3相システムから高電圧eパワー・トレイン用のトラクション用インバータまで、ブラシレスDC(BLDC)モータは長時間にわたる連続デューティ・サイクルを要する自動車アプリケーションに最適です。この動作には、高度な制御アルゴリズムが必要なため、ブラシ付きDCモータ駆動よりも高い演算能力が必要です。

新エネルギー車(NEV)分野では、さらに厳しいCO2排出要件と安全機能への準拠が求められているため、スタータ・ジェネレータ(BSG)や、各種バッテリ式EV(BEV)用のきわめて効率的な3相インバータによるeターボ・チャージャ・モータのようなマイルド・ハイブリッド用のシステムの電気化につながります。

STの広範なポートフォリオにより、BLDCモータ制御設計に対応する包括的な提案を提供します。: ISO26262 ASIL-D準拠のリアルタイム・アプリケーション用に設計された自動車向け高性能SPC5マイクロコントローラから、インテリジェントVIPowerスイッチ、SiCパワーMOSFET、6段階/FOC制御BLDCモータ用3相ゲート・ドライバ、EFTまたはスパイクに対するESDおよびTVSプロテクションまで、STは、さまざまな自動車の設計において、最も先進的コスト効率に優れたモータ制御ソリューションの提供が可能です。

    • Based on the EVAL-L99ASC03 evaluation board designed for sensorless 3-phase BLDC motor control, the system features enhanced power management power supply functions including various standby modes. The motherboard, based on an STM8 microcontroller, provides the logic section for monitoring and driving the L99ASC03G 3-phase motor pre-driver assembled in the daughterboard. 

      ST also provides dedicated user-friendly software with a Graphic User Interface (GUI) that enables the user to set L99ASC03G parameters while displaying device information in real time.

      Developers can easily evaluate their brushless DC motor control solution for a variety of circulation and booster pump applications for coolant, water, fuel or oil lines.
