Ward Leonard Method Of Speed Control Or Armature Voltage Control Ward Leonard Method of speed control is achieved by varying the applied voltage to the armature. This method was introduced in 1891. The connection diagram of the Ward Leonard method of speed control of a DC shunt motor is shown in the figure below.
International Journal of Engineering and Techniques Volume 2 Issue 6, Nov – Dec 2016 RESEARCH ARTICLE OPEN ACCESS DC MOTOR SPEED CONTROL USING MICROCONTROLLER 1 2 Ms Sarita S Umadi, Dinesh Patil (Electrical Electronics Engineering, AITRC,Vita (Mechanical Engineering, BIT, Barshi) Abstract: The aim of this paper is to control the speed of DC motor.
DC Motor Equivalent circuit The schematic diagram for a DC motor is shown below. A DC motor has two distinct circuits: Field circuit and armature circuit. The input is electrical power and the output is mechanical power. In this equivalent circuit, the field winding is supplied from a separate DC voltage source of voltage Vf.
A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years to operate motors in commercial and industrial buildings.

DC Motors speed synchronization for rolling mills The project aims at designing a system which is capable of synchronizing the speed of the slave motor (motor2) with the master motor (motor1). This system finds very useful in paper mills, steel industries etc..,. The master motor speed can be set
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.
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.
