Speed Regulation of a DC Motor
Speed regulation is defined as the difference in speed from no load to full load, expressed as a fraction or percentage of full load speed.
Therefore, according to the definition per unit (p.u) speed regulation of a DC motor is given as,
Speed Regulation = Nno load – N full load / Nfull load
Similarly,
Speed regulation % = Nno load – N full load / N full load x 100
Therefore,
Percent speed regulation = per unit speed regulation x 100%
A motor with essentially constant speed at any load less than full rated load has good speed regulation.
Speed Regulation of DC Motor
At the point when a DC motor gets stacked, its speed decreases gradually which is not beneficial for the machine. So the distinction between no-heap and full-load rates not being most important means it is not likely to make a difference. An engine that can keep an almost consistent speed under changing burdens is said to have major areas of strength, and that implies that the distinction between no heap and full burden speed is little. Speed guidelines for extremely durable magnet DC motors are great, going somewhere in the range of 10 and 15%, but DC shunt engines are somewhat under 10%. DC series motors have bad guidelines. For a compound DC motor utilizing DC total compound, the speed guideline is around 25%, though the differential compound has a superb value of 5%.
