Apparatus for and method of winding layers of wire on a rotor or stator of a rotary electric generator or motor

摘要

An apparatus for winding layers of wire on a pole of a rotor or stator of a rotary electrical generator or motor comprises a needle mounting member movable substantially axially of the rotor or stator and a needle rotatably mounted on the mounting member and extending transversely thereto. The needle is rotatable about an axis transverse to the direction of movement of the mounting member. The needle has a groove defining an outlet path for the wire to one side of the axis of rotation of the needle. A method of winding layers of wire on a pole of a rotor or stator of a rotary electrical generator or motor comprises the steps of providing a needle having a groove defining an outlet path for wire to be wound in layers, moving the needle over a winding path and causing the needle to rotate at positions in the winding path.
