Motor component alignment method

An alignment method for aligning a plurality of U-shaped electrical conductors as stator conductors of a rotating electrical machine in a state in which turn sections provided to an apex portion thereof are alternately overlapped, by arranging the plurality of electrical conductors in an annular shape, the method comprising:

• causing the plurality of the electric conductors to move in a direction to reduce the diameter of the annular shape by utilizing a plurality of grippers and a plurality of slide rails, the plurality of grippers gripping the respective plurality of electric conductors, and the plurality of slide rails extending radially around a central axis of the annular shape to slidably guide movement of the plurality of grippers in a radial direction, and
• aligning the plurality of the electrical conductors by causing each of the plurality of the electrical conductors to rotate via rotation of the plurality of grippers about a shaft that is parallel to the central axis of the annular shape, while causing the plurality of the electric conductors to move towards the center of the annular shape via movement of the plurality of grippers in the radial direction,
• wherein each of the plurality of the electrical conductors is arranged in a state of maintaining a predetermined correcting rotation of a predetermined angle about the shaft that is parallel to the central axis of the annular shape by utilizing a correction groove and a pin provided correspondently, when aligning by reducing the diameter of the annular shape.
