MECHANICALLY AND ELECTRICALLY INTEGRATED MODULE

摘要

An inverter apparatus is incorporated integrally into a non-load-side of a motor such that an inverter cooler is interposed, and a non-load-side end frame of the motor includes: a flat base portion; a cylindrical non-load-side bearing portion that is disposed so as to protrude axially from near a center of a front surface of the base portion that faces a rotor, and that houses and holds a non-load-side bearing into which a non-load-side end portion of a rotating shaft of the rotor is mounted; and an annular first flange portion that is disposed so as to protrude axially from an outer circumferential edge portion of the front surface of the base portion so as to contact a non-load-side end surface of a cylindrical portion and a cylindrical member.

主权项

1. A mechanically and electrically integrated module comprising:
a rotary electric machine that comprises:
a housing that comprises:
a cylindrical circumferential wall portion; anda load-side end frame and a non-load-side end frame that are disposed on two axial ends of said circumferential wall portion;a stator that comprises:
an annular stator core; anda stator coil that is wound onto said stator core,said stator being held by said housing such that said stator core is housed in said circumferential wall portion in an internally fitted state; anda rotor that is rotatably supported by said load-side end frame and said non-load-side end frame so as to be disposed on an inner circumferential side of said stator; and an inverter apparatus that converts direct-current power into alternating-current power, said inverter apparatus being incorporated integrally into a non-load-side of said rotary electric machine such that an inverter cooler is interposed, wherein: said non-load-side end frame comprises:
a flat base portion;a cylindrical non-load-side bearing portion that is disposed so as to protrude axially from near a center of a front surface of said base portion that faces said rotor, and that houses and holds a non-load-side bearing into which a non-load-side end portion of a rotating shaft of said rotor is mounted; andan annular first flange portion that is disposed so as to protrude axially from an outer circumferential edge portion of said front surface of said base portion so as to contact a non-load-side end surface of said circumferential wall portion; and at least one of said non-load-side bearing portion and said first flange portion is disposed such that an axial position thereof overlaps with said stator coil so as to be in a state of non-contact with said stator coil.
