DC motor voltage regulation is a technique for adjusting the voltage of a DC motor by changing the armature voltage of a DC motor. This technology has now been applied to DC motors and has been widely developed. Actually, various DC motors can be adjusted by changing the armature voltage. DC motor voltage regulation and voltage regulation has the advantages of good speed stability, fast response, and wide voltage regulation range when the load changes. When the power supply voltage is continuously adjustable, stepless voltage regulation can be realized. This method is characterized by better voltage regulation performance.
