Speed up Control: With this sort of machine, regulating the speed is easy. The greater the armature voltage, the quicker the rotation, which suggests a faster rate. The voltage will certainly increase in conjunction with the horsepower. Many DC commercial electric motors will certainly execute over a rate variety of 20:1, to approximately 5 % to 7 % of the base rate. They are developed with changeable speed operation in thoughts, so they have heat control features that enable reduced operating rates.
Tons Control: The load, or twist, control is basic. The output torque is symmetrical to the present, so if you limit the existing, you limit the twist it could take. This is one reason why these DC engines are used for applications such as textile manufacturing.
