直流电机初始化正反转刹车代码

直流电机的初始化、正反转和刹车控制通常涉及到硬件连接和软件逻辑，这里提供一个简化版的伪代码示例，用Python语言来表示，假设我们有一个基本的控制结构：

class DCMotor:
    def __init__(self):
        # 初始化电机参数和连接状态
        self.motor_direction = 'forward'
        self.brake_state = False

    def set_direction(self, direction):
        if direction == 'forward':
            self.motor_direction = 'forward'
            self.enable_driver(positive=True, negative=False)
        elif direction == 'reverse':
            self.motor_direction = 'reverse'
            self.enable_driver(positive=False, negative=True)
        else:
            self.brake()
        
    def enable_driver(self, positive, negative):
        # 设置驱动器的正负极信号
        if self.motor_direction == 'forward':
            driver.set_signal(power=positive, brake=negative)
        else:
            driver.set_signal(power=negative, brake=positive)

    def brake(self):
        self.enable_driver(power=0, brake=True)  # 刹车时断开动力并接通制动电路
        
# 使用例子
motor = DCMotor()
motor.set_direction('forward')  # 正转
motor.set_direction('reverse')  # 反转
motor.brake()  # 刹车
