A DC motor has a handful of advantages, Torque and Speed Difference. Do you know power motor is, the answer is rather simple, it is an object that changes power directly into mechanized energy? The mathematics at the back of it is more technical, but also for practical reasons all it can turn one type of energy into another sort of energy. To be more accurate we can say a motor is a gadget that produces torque.
Torque can be a turning pressure that generates rotation of the shaft. DC motors can form a continuous torque over a wide speed range.
For any DC motor: Torque is certainly proportional to armature current – this implies controlling rpm requires controlling the motor DC current – very easily done with a straightforward DC motor.
You can change the speed by changing the field voltage, the armature voltage or the two. To do this if you operate your engine at a basic speed of 2000 rpm and a voltage of 500v if you decrease the armature voltage to 250v your motor can run at 1000 rpm.
You cannot boost the field voltage to secure a speed under base swiftness; this would trigger the field to get hot at more than rated current. DC motors operating with a running armature voltage and field has continuous horsepower capability over their particular speed range.
