摘要： PROBLEM TO BE SOLVED: To improve the efficiency of an electric motor having a split core.
SOLUTION: A core 20 split with a foundation portion 32 split and an erect portion 34 are fastened with bolts 36. This brings a joint surface 46 of the foundation portion 32 to the erect portion 34 into close contact with each other, thus reducing magnetic resistance and improving efficiency. The bolt 36, made of non-magnetic material, reduces the number of magnetic fluxes passing through the bolt, thus reducing an eddy current developed in the bolt. Moreover, a ratio (H/D) of a distance H between a teeth front end face 48 and a bolt head top face 50 to a diameter D of a bolt hole is set at ≤0.3.

摘要： PROBLEM TO BE SOLVED: To reduce the loss due to an eddy current by reducing the eddy current generated in teeth in case that a core is composed of a plurality of core segments. SOLUTION: The stator core is composed of the plurality of core segments 32 segmentalized by the cleavage plane 30 at cleavage planes passing inside each tooth 24. The cleavage plane 30 segmentalizes a tooth 24 that it passes, in the direction of array of the tooth 24. The cross section orthogonal to the magnetic flux 36 of the tooth 24 is divided in the circumferential direction of the core by the cleavage plane 30, and the cross section of the tooth 24 where an eddy current 34 circulates decreases, so it can reduce the eddy current 34 generated in the tooth 24.
