中文说明：直流电机是任何一类电机，直流电源转换为机械动力。最常见的类型依赖于由磁场产生的力。几乎所有类型的直流电动机都有一些内部的机制，机电或电子、 周期性变化部分的电机电流流动的方向。大多数类型产生旋转运动;直线电机直接产生力和运动在一条直线。 这些文件允许电机直流二进制和永磁电机的模拟。
English Description：
A DC motor is any of a class of electrical machines that converts direct current electrical power into mechanical power. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor. Most types produce rotary motion; a linear motor directly produces force and motion in a straight line. These files allow the simulation of Motor DC Binary and Permanent Magnet Motor.
