抱闸控制器，用PWM方式控制电机抱闸，在有效开通抱闸情况下缓解抱闸发热(The brake controller, using PWM to control the motor brake, brake in effective opening off brake fever)

双路电机驱动原理图及PCB布线图，两个电机单独控制，可以实现电机的正反转，电机的PWM速度控制。(Dual motor drive schematic diagram and PCB wiring diagram, two motors separately control, can achieve positive and reverse motor, motor speed control of PWM.)

基于STM32F407ZGT6，PWM电机驱动及控制，集成MPU6050，预留蓝牙接口(Based on stm32f407zgt6, PWM motor drive and control, integrated mpu6050, reserved Bluetooth interface)
