I don't really know what you're asking. An observation though: if I have interpreted the drawing correctly, there is an odd number of poles. I haven't seen that before.
solid copper as opposed to what... turns and strands?
turns serve to increase the voltage (for a given flux density and coil span area) in order to match the system voltage.
turns also serve to minimize eddy current and deep bar effect (if you're comparing to solid hunk of copper). Stranding also serves to minimize eddy current.
I'd respectfully suggest, the best thing to do is study traditional winding construction. There is a lot that goes into it… doubtful you will come up with anything better until you have studied what has come before.
"There is a lot that goes into it… doubtful you will come up with anything better until you have studied what has come before."
That is so true in in all aspects of life and engineering.
In addition to the observations about the odd number of pole pairs and the non-practicality of having three solid strands (how are you going to connect them?) it is also a very bad design when it comes to iron plates (or are you going to use solid iron, too?) and that is that there is almost no iron left for the magnetic flux.
Back to the drawing board. Or buy motors from the guys that know how to build them.
Had a 600 kW generator that was wound with flat copper strips instead of copper wires to reduce eddy currents in the winding conductors.
Good design practice is a series of compromises. Some of the compromises are voltage, and winding conductor size, number and shape. A single solid bar will be rejected on the basis of the extremely low voltage required (extra transformer cost and losses) I2R losses due to the high current and more I2R losses due to eddy currents in the solid conductors.
The idea may be technically doable but is an economic disaster.
BUT don't let me stop you.
You can easily procure a three phase motor. Count the turns as you remove the existing windings.
For example if there are 50 turns, divide the voltage by fifty and multiply the current by 50.
Install your solid bars and find or build a transformer to deliver the required current at the proper voltage.
The motor will probably work. let us know how it performs and the cost savings over a conventionally wound motor. Don't forget to test for losses in both the motor and the transformer. Don't forget to factor in the cost of the transformer.
By the way; shaded pole motors use a single solid conductor for the shading coil and squirrel cage induction motors use solid conductors in the rotor.
Squirrel cage rotors may have the squirrel cage winding formed by casting aluminum in suitably shaped holes in the stator or may use solid copper bars. The effective frequency seen by the squirrel cage winding is very low and this greatly reduces eddy currents in the squirrel cage conductors.
Solid windings are not new and are used when appropriate.
