The speed adjustment scheme of wholesale 12 volt dc motor generally has the following three ways:
1, change the armature voltage;
2, change the excitation winding voltage;
3, change the electrical pivot resistance.
The most commonly used is the voltage regulation system, IE 1(change armature voltage).
The utility model relates to a modular DC motor governor, which integrates power supply, control and drive circuits, adopts a three-dimensional structure layout, adopts a micro-power consumption element in the control circuit, and uses a photoelectric coupler to achieve the isolation transformation of current and voltage. The proportional constant, integral constant, and differential constant of the circuit are adjusted with the PID adapter. The small size and light weight of the governor can be used alone or directly installed on the DC motor to form an integrated DC speed regulating motor, which can have all the functions that the governor should have.
