I've never heard the term "mesh wound" for something like a 200HP induction motor. "Mush wound" is sometimes used in small frame AC motors, it's a way of randomizing the coil connections when you have an odd number of slots, motor guys understand that better. But I don't think that would apply to a 200HP motor. Mesh wound is something I've heard in describing servo motors, although I'm not sure what that means for them. Still wouldn't apply here.
"Random wound" vs "form wound" is a more likely choice at that size. Form wound means the windings consist of square conductors that are individually wrapped, then stacked evenly and consistently in the slots throughout the stator. They are a much better design concept for larger motors, but at something like 200HP would likely be prohibitively expensive for the average application. Random wound just means the stator coil windings are done with insulated round conductors wound into coils that are then placed into the slots and varnished afterward. With random wound, there are slight inconsistencies in the overlaps of conductors that can lead to becoming failure points, especially as the motor ages and/or is subjected to stresses. But it's also far far more economical. Most COTS AC induction motors under 500HP are going to be random wound.
