単相誘導モータは、1つのステータ・コイルで設計されたブラシレス・モータです。STは、トライアック、サイリスタ、ACスイッチなど、最先端の堅牢なデバイスを提供して、最終アプリケーションのコストおよび性能要件に応じた様々なモータ速度調整を可能にしています。
- 双方向駆動
位相シフト・コンデンサを常置してモータを使用する場合、2つのステータ巻線のどちらかと直列に位相シフト・コンデンサを接続する2つのACスイッチによって回転方向を逆転できます。
- 位相制御駆動
STは、革新的なトポロジでモータ速度を制御する静音かつコスト効率に優れた可変速駆動を提供しています。シンプルな位相制御スイッチを使用し、モータ・トルクを変更することで速度調整を行います。

STEVAL-IHT001V2 Cold thermostat kit based on AC switches and the STM8S Quick view

主な特徴

  • Low-cost solution for spark-free thermostats:
    • No need for a sealed version
    • Low-cost STM8S microcontroller for thermostat control
    • Low-cost capacitive power supply
  • High efficiency:
    • Refrigerator consumption reduction by adjusting and reducing the hysteresis threshold of the temperature
    • Improved efficiency by turning on the defrost resistor only when it's useful and not at each OFF cycle of the compressor (as done in some mechanical thermostats)
  • High system immunity:
    • Overvoltage protected ACS switches: ACST610-8FP for compressor control, ACS110-7SN for defrost resistor and ACS102-6TA for light bulb and fan
    • Class A criteria for IEC 61000-4-4 up to above 3 kV levels
  • Flexibility:
    • Development: program setting with PC interface to change firmware variables
    • Industrialization: end-of-production MCU programming thanks to FLASH, for soft upgrade and efficient MCU stock management
  • RoHS compliant
