Speed control of dc series motor. Runs quietly with little noise. 12,000 lb. The speed of a DC series motor is given by, $$\mathrm {N \: \varpropto \: \frac {E_ {b}} {\varphi}}$$ $$\mathrm {\Rightarrow \: N \: = \: K \left (\frac {V \: - \: I_ {a} (R_ {a} \: + \: R_ {se})} {\varphi}\right) \:\: \dotso \: (1)}$$ Hence, it is clear from the eq. 7 feet per minute with no load. Weakening the field causes increase in the speed of the motor, and strengthening the field reduces the speed. See the circuit diagrams and examples of different speed control methods. Field Control Methods The speed of the DC series motor can be controlled by varying the field resistance of the motor. rated line pull powered by a 6 HP (12V) DC series wound motor Line speed of 2.
