Lecture 25 Simple Machine Analysis Consider a stator and a rotor with a winding each. Let us define now the stator and rotor axis to be perpendicular to the winding directions as shown in the figure. Figure 1 - Machine axis q is the angle between the stator and the rotor axis. Figure 2 - Stator and rotos axis Clearly, if the rotor is turning at a constant angular speed ωmthen the angle between the rotor and the stator is time dependant. ( )0mttθωθ=+
