What Is a Current Regulator?
A current regulator is an electronic device that regulates the current in a circuit. A movable iron core is added between the current-regulating ministerial coils as a magnetic branch.

- In general,
- (1) Follow-up effect-As the regulator of the inner loop, its role is to make the current closely follow its given voltage (ie the output of the regulator of the outer loop) during the adjustment of the outer loop speed.
- (2) Anti-disturbance effect-It plays a timely anti-disturbance effect on the fluctuation of the grid voltage.
- (3) Speed up the dynamic process --- During the speed dynamic process, ensure that the maximum current allowed by the motor is obtained, thereby speeding up the dynamic process.
- (4) Over-current automatic protection function --- When the motor is overloaded or even blocked, the maximum value of the armature current is limited to play a fast automatic protection function. Once the fault disappears, the system will automatically return to normal immediately. This role is very important for the reliable operation of the system.
