Project - Speed Control of a Direct Current (DC) motor

1. speed control of a direct current (dc) motor

Dc motor can control speed by manually and automatically by control device

the different in speed regulation where the speed is trying to be maintained or regulated against the natural change in speed due to change in load on the shaft so speed can be changed.

the terminal voltage of the armature v,the external resistance in armature circuit Ra.

the flux per pole,so terminal voltage and external resistance involves a change in the magnetic field,speed control of dc motor has two control methods

armature control methods

fields control methods.
