The relationship between your rotating rate and you will torque out of a beneficial DC system will be revealed by drawing revealed from inside the Fig. 2.several .
In the event the likewise have voltage try constant, new drawing implies that DC system services are going to be portrayed by the a straight line going in the fresh guidelines from ideal leftover so you can base best.
You can read the brand new zero-weight angular rate in the higher left-hand stop of one’s line plus the starting torque from the all the way down correct-hands avoid. Concurrently, if for example the have current goes up, that it line movements in parallel on the the upper best-hands place; and, alternatively, for the the lower remaining-give corner should your voltage drops.
Matchmaking anywhere between Rotating Rates and you may Torque
Now, i have learned it have several other element in which rotating price expands in the event that voltage was improved. This might be slightly a handy characteristic with respect to dealing with rotation.
Another noteworthy characteristic is that the DC motor generates torque proportional to the current even if the rotating speed is zero because of the T = KT relationship (equation 2.3). Read more
