the speed of the DC motor. Now the output speed of motor is measured by Tacho-generator. The tacho voltage we will get from the tacho generator contains ripple and it will not be perfectly dc. So, we require a filter with a gain to bring Tacho output back to controller level. The basic block diagram for DC motor speed control is shown in

DC Motor Equivalent Circuit. A DC motor electrical equivalent circuit is divided into two circuits: field circuit and armature circuit. Field circuit is responsible for the magnetic field and is supplied with a separate DC voltage V f.The resistance and inductance of the field winding are represented by R f and L f.As a result of the voltage, a current I f is produced in …

Torque-Speed Characteristic of Cumulatively Compounded DC Motor In this motor, one part of flux has a constant value and the other is directly proportional to the armature current. Due to this the torque for the cumulatively compound motor has high value than shunt motor starting torque but less than the series motor starting torque.

Rolling of cloth should be synchronized with the speed of weaving spindle to avoid damage and similarly motors-speed synchronization is vital in a conveyor- belt driven by multiple motors. Abrupt load (or power-supply) variations may cause hunting or oscillatory behavior in dc machines. This behavior can be detrimental to the process.
