What are some common applications of DC motors used in our daily life?
In our daily life, they are used in printers, fuel pumps, and electric vehicles. While in spacecraft applications, they are used in solar airplane, electric aircraft, and propulsion systems.
Why are DC motors used?
DC motors offer highly controllable speed. By changing the armature or field voltage it’s possible to achieve wide speed variation and with this level of controllability, DC motors offer the precision required by a wide range of industry applications.
What are applications of a DC separately excited motor?
Separately excited DC motors are often used as actuators in trains and automotive traction applications. For their constant speed characteristics, shunt DC motors are used in fixed speed applications such as fans. square of armature current), they can be used in applications that require high starting torque.
What are the 3 types of DC motors?
There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
What is the main advantage of using DC motor drive?
DC motors have the advantage of: higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and they are easier and cheaper to control than AC.
