SCM stm32f103rb, BLDC DC motor controller design, schematic diagram, source code and circuit scheme
2022-06-24 07:57:00 【1ShyJn25】
be based on STM32 BLDC Design of Brushless DC motor controller , The schematic diagram and source code are attached . The source code is based on free and open source CoOS(UCOS similar ) Written on the operating system , While learning the control of brushless motor, you can also learn the knowledge of operating system . Also available for Matlab Of GUI The serial port receiving program and open source code , Receive speed and current information in real time , Easy PID test , And there are CAN(TJA1050) Interface . At the same time, you can modify and learn by yourself Matlab Of GUI Programming .
1．STM32F103RB processor The clock 72M Flash 64K RAM 20K
2．MOSFET SUD35N05-26L 55V 35A Rds=0.02
3. MOSFET drive IR2101S
