... rotor.Principle of operation of this assembly is illustrated by means of Fig. 1. Rotor winding is shownin a very simplified manner, as consisting of just one coil, connected to two segments of thecommutator. ... current) and to the speed of rotation,through a constant determined with constructional features of the machine. Speed of rotation ωis the so-called angular speed of rotation in [rad/s] and ... However, if the load torque is speed dependent, thenchange of load torque implies quadratic change of armature current, while in the case of theseparately excited motor the change is linear.Example...
