众所周知,电机本质上就是利用磁场将电能转化为机械能。简单地说,操作者给电机输入电能,就能得到机械运动的输出。绝大部分的小车机器人都是由直流减速电机驱动的。从它的名字就可以知道,直流减速电机其实是由一台依靠直流电提供动力的电机和一个减速箱连接而成的。其中,减速箱的作用就是把电机的转动速度降下来。然而,为什么要把电机的转速降下来呢?这是有科学道理的。我们可以来计算一道简单的算术题:假设机器人小车的轮子直径约 As we all know, the motor is essentially the use of magnetic fields into electrical energy into mechanical energy. Simply put, the operator to the electrical input power, you can get the mechanical movement of the output. Most trolley robots are powered by DC gearmotors. From its name you can see that the DC gearmotor is actually connected by a DC motor and a gearbox. Among them, the role of gear box is the motor speed down. However, why should the motor speed down? This is scientific. We can calculate a simple arithmetic question: Suppose the robot car’s wheel diameter is about
