METHOD FOR PRODUCING A ROTOR OR A STATOR OF AN ELECTRIC MACHINE FROM SHEET BLANKS |
摘要 |
<p>Sheet-metal blanks for rotors or stators of electrical machines are cut from rolled sheet-metal strips with a magnetic preferential direction and layered to form a laminated rotor core or laminated stator core. To compensate largely for a magnetic anisotropy of the laminated rotor core or laminated stator core, the sheet-metal blanks, when they are not centrosymmetrical, are cut out together congruently in a single cutting operation, from rolled sheet-metal strips stacked one above the other and rotated relative to one another by an angle.</p> |
