一、28BYJ-48 步进电机
28BYJ-48是一款5线单极步进电机,运行电压为5V。
根据数据表,当28BYJ-48电机在全步模式下运行时,每步对应于11.25°的旋转。这意味着每转有32步 (360°/11.25° = 32)。
如上图所示,步距角=5.625°/64
意思就是每64个脉冲步进电机就会转5.625度,因此我们很容易得出以下计算公式:
电机转一圈有360°,那么转一圈的脉冲数 = 360 / 5.625 * 64 = 4096 个脉冲。
进而很容易得到以下角度与脉冲的转换:
/* Rotation_Angle:旋转角度 返回:Motor_Pulse 根据公式计算得出的脉冲个数 */ int Motor_Angle_Cal(int Rotation_Angle) { Motor_Pulse = (int)((double)(Rotation_Angle / 5.625) * 64) ; return Motor_Pulse ; }

main.c
/* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include "Motor.h" /* USER CODE END Includes */
while
步进电机简单正反转
/* USER CODE BEGIN WHILE */ while (1) { //1反向 0正向 direction = 1; for(uint8_t step=0;step<=8;step++){ //控制步进电机旋转 MOTOR_CONTROLD(step, direction); HAL_Delay(1); } /* USER CODE END WHILE */
