Rotary electric machine

Abstract

A motor includes a driving shaft, a rotor attached to the driving shaft, and a stator having a substantially cylindrical stator core provided around the rotor, and a plurality of coils wound around the stator core in a distributed winding manner The stator core includes three separated stator core parts aligned along a peripheral direction, and each of the coils is disposed so as not to lie astride any two of the three separated stator core parts. At least one coil end of the plurality of the coils is disposed to pass through an inner side relative to an inner peripheral surface of the stator core.

1 . A rotary electric machine, comprising:
 a driving shaft;   a rotor having a substantially cylindrical rotor core attached to the driving shaft; and   a stator having a substantially cylindrical stator core provided around the rotor, and a plurality of coils wound around the stator core in a distributed winding manner, wherein   the stator core includes a plurality of members aligned along a peripheral direction,   each of the coils is disposed so as not to lie astride any two of the plurality of the members, and   a coil end of at least one of the plurality of the coils is disposed to pass through an inner side relative to an inner peripheral surface of the stator core.   
     
     
         2 . The rotary electric machine of  claim 1 , wherein
 a coil end of at least one of the plurality of the coils is formed in a linear shape when viewed in plan.   
     
     
         3 . The rotary electric machine of  claim 1  or  2 , wherein
 the stator core has raised/recessed portions, and the rotor core has raised/recessed portions to face the raised/recessed portions so that gaps are formed between the stator core and the rotor core to be continuously arranged in a staggered manner along a radial direction and an axial direction.
