Direct current (DC) motors have been widely used in many industrial applications such as electric vehicles, steel rolling mills, electric cranes, and robotic manipulators due to precise, wide, simple and Continuous control characteristics. ... FLOW CHART DIAGRAM OF SPEED SYNCHRONIZATION OF MOTORS.
Jul 11, 2019· Therefore speed of the 3 types of DC motors – shunt, series and compound – can be controlled by changing the quantities on the righthand side of the equation above.. Hence the speed can be varied by changing: The terminal voltage of the armature, V.; The external resistance in armature circuit, R a.; The flux per pole, φ.
Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills.
