    的转动方向有两种方法: There are two ways to change the direction of rotation of a DC motor :

    1.Change the direction of the magnetic field

    2.Change the current direction (that is, change the positive and negative poles of the power supply)

    If the direction of the current and the direction of the magnetic field change together, then the direction of rotation of the DC motor does not change.

    The principle of a DC motor is to change the direction of the current in the coil. A commutator can achieve the purpose.
