DC motors provides rotatory motion based in a current input. The equivalent electric and mechanical systems of the DC motor is shown below. b.o L R w V Di sinna Τ. ω The torque generated by a DC machine T, is proportional to the stator current i and the strength of the rotor magnetic field. If the rotor magnetic field is provided by a permanent magnet then the field can be considered constant and the torque turns proportional to the stator current multiplied by a constant K . This constant is equal to the constant that multiplies the back EMF e of the machine. The back EMF of the machine is proportional to the angular velocity w of the shaft. The equations that define this system are listed below T = Ki e=ko do J +bo=T= Ki dt di L + Ri=y-Ko dt Question 2: What is the transfer function that relates the angular velocity 0 of the motor with the applied voltage V in the stator circuit? Exercise 2: Using the values in the table below J moment of inertia of the rotor 0.01 kg.m^2 b motor viscous friction constant 0.1 N.m.s KEK electromotive force constant 0.01 V/rad/sec KEK motor torque constant 0.01 N.m/Amp R electric resistance 1 Ohm L electric inductance 0.5 H
