Torque versus armature current (T v/s I a); Speed versus armature current (N v/s I a); Torque versus speed (T v/s N). DC motors were the first type of motor widely used and the systems (motors and drive) initial costs tend to be typically less than AC systems for low power units, but with higher power the overall maintenance costs increase and would need to be taken into consideration. Get it as soon as Tue, Feb 25. • It has a PM rotor type. Brushed, wound-field DC motors have formed the primary type of DC motor used in pump applications for many years. Siemens Integrated Safety – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow. Earlier, the variable DC voltage for the speed control of an industrial DC motor was generated by a DC generator. Starting in the late 1880s, Thomas Edison and Nikola Tesla were embroiled in a battle now known as the War of the Currents. From electric shavers to automobiles – DC motors are everywhere. dIdt increases and hence V L increases B. In our previous blog article we took a look at how a DC and an AC motor works and described how you can build your own basic DC motor.
