    Low voltage dc servo motor speed control, often say is he excitation brushless dc motor speed control, according to the dc motor speed equation of the rotational speed n = (armature voltage U - voltage current Ia * resistance Ra) present (constant Ce * air-gap flux Φ), because the armature resistance of Ra is very small, so the voltage current resistance Ra material Ia * 0, such speed n = the armature voltage (U) present (constant Ce * air-gap flux Φ), as long as the air gap flux Φ safe adjusts the armature voltage U, will be able to adjust the dc motor speed n; Or in the armature voltage U safe adjusts the air-gap flux Φ, same can adjust the speed of the motor n, the former is called constant torque control, which is called constant power speed regulation.
