Mechanical Characteristics Next, we will apply Newton's law to write the differential equations that model the mechanical portion of the DC motor. Write here the diff eqs. of the mechanical portion: Write here Newton's law (sum of the torques of the motor must equal zero): Write here the diff eqs. of the mechanical portion: Note that the electromagnetic torque is proportional to the current through the armature winding and can be written as the product of the velocity constant (K)times the current. The torque constant K depends on the flux density of the fixed magnets.
