简介

在此参考设计中,瑞萨电子提供具有旋转变压器位置控制功能的步进电机解决方案和可选的 BLDC 电机解决方案。 步进电机解决方案实现了用于办公自动化和工业应用的高性能电机驱动装置,例如可用于扫描仪、多功能打印机和自动存款机。 同时 BLDC 电机解决方案实现了用于自动引导车 (AGV)、小型车、服务机器人和电动自行车应用的高性能电机驱动装置。

系统优势:​

  • 使用包含示例软件的整体解决方案来提高开发速度。
  • 通过将光编码器更换为旋转变压器来降低 BOM 成本。
  • 步进电机解决方案
    • 通过带有旋转变压器位置信息的伺服控制实现无失步。实现无失步裕度,最大程度地提高电机扭矩,缩小电机尺寸,并通过减少齿轮(减速器)来降低 BOM 成本。
    • 通过减小转矩脉动的伺服控制实现低噪音和低振动。
  • BLDC 电机解决方案
    • 使用高精度位置信息和高分辨率旋转变压器,通过伺服控制来实现精细运动/停止控制。
    • 通过提高位置分辨率和优化速度响应,来抑制旋转不均的情况并减少造成震动的波纹。
