The Investigation of Poles Shape of the Technological Rotating Magnetic Field Inductor
The inductor of technological rotating magnetic field must create the magnetic flux density equal to 0,1–0,2 T in the big air gap. The uniformity and intensity of created field strongly depend on the inductor poles geometry. The mean value of magnetic flux density can be increased about 45 % expending the poles in circumferential direction. The influence of pole magnetic resistance to the magnetic field distribution along axis can be evaluated, using the theory of distributed-parameter line. Elongating the poles along inductor axis the unit active zone can be extended, but the poles must be thickened and its relative permeability must be increased.
