DC motors offer better speed control than their AC counterparts. If you're working with heavy load systems, the ability to control the speed precisely can mean the difference between a successful job and a burned-out motor.

DC Motor: Futures of DC Motors: 1- Most of the electrical machines in service are AC types. 2- DC machine are of considerable ind ustrial importance. 3- DC machine mainly used as DC m otors and ...Even speed control is simple: Just adjust the terminal voltage, often using a local potentiometer. Additionally, until the late 1980s, when the variable frequency drive (VFD) was fully developed, DC motors were the best choice for variable speed control, and this remains a well-supported option. Torque at low speed
