GEOMETRY OF ROTOR END RING AND STATOR END TURNS |
摘要 |
A method of making an AC induction motor includes: providing a rotor and a stator for the AC induction motor; determining, for different geometries of an end ring of the rotor, a location of a first centroid of current density in the end ring; determining, for end turns of the stator, a location of a second centroid of current density in the end turns; selecting a geometry for at least the endring of the rotor so that an axial distance between the first centroid of current density and the second centroid of current density is minimized; and assembling the AC induction motor, wherein the end turns and the end ring have the selected geometries. |

1. A method of making an AC induction motor, the method comprising:
providing a rotor and a stator for the AC induction motor; determining, for different geometries of an end ring of the rotor, a location of a first centroid of current density in the end ring; determining, for end turns of the stator, a location of a second centroid of current density in the end turns; selecting a geometry for at least the endring of the rotor so that an axial distance between the first centroid of current density and the second centroid of current density is minimized; and assembling the AC induction motor, wherein the end turns and the end ring have the selected geometries. |
