RTK0EML2C0S01020BJ 有效

用于 RAJ3060xx 电机控制集成电路的 BLDC 电机控制评估系统

该套件使用 RAJ306010 电机控制集成电路评估 BLDC 电机系统。 该套件包括一块安装RAJ306010的电路板、一个小型 24V 电机和一根连接电缆。

RAJ306010 最初配备了使用霍尔集成电路进行 120 度导通控制的示例代码，只需连接 24V 直流电源和附带的电机即可进行电机控制的基本评估。 此外，还可连接和评估用户准备的电机和 MOSFET。

BLDC 电机与标准有刷电机控制要求不同。 更多信息和指南，请参阅 BLDC 电机控制算法页面。

所需设备：

  • 电源 24V/2A
  • 仿真器 E2、E2 Lite、E20、E1
  • USB mini-B 型
