Abstract
A connection member for supplying a stator winding with a current is constituted by covering a bus bar with a insulating resin. The bus bar is formed in an arc-like shape in the thickness direction of a belt-shaped conductor. Additionally, a weld zone formed on the bus bar has a projection portion projecting in the width direction, a first bent portion bent outside the arc from the projection portion in the thickness direction, and a second bent portion with the tip end thereof folded back in the width direction to allow the tip end of the second bent portion to be welded to a terminal on the stator winding.
Claims5
A motor stator, comprising:
- a stator core formed by laminating thin plates and having a plurality of salient poles projecting in a radial direction;
- a stator winding wound around each salient pole of the stator core;
- and
- a connection member connected to the stator winding to supply the stator winding with a current,
- the motor stator being characterized in that:
- the connection member is formed by covering a one or more than one bus bar with an insulating resin, each bus bar being a belt-shaped conductor formed in an arc-like shape in a thickness direction of the belt-shaped conductor and covered with the insulating resin at least in a portion opposing a coil end of the stator winding;
- a weld zone is formed on the bus bar;
- and
- the weld zone has a projection portion projecting in a width direction, a first bent portion bent outside the arc from the projection portion in a thickness direction, and a second bent portion with a tip end thereof folded back in the width direction to allow the tip end of the second bent portion to be welded to a terminal on the stator winding.
