The present invention manufactures a steel sheet for a rotor core for an IPM motor, wherein the steel sheet has a magnetic flux density B.sub.8000 of 1.65 T or more as measured when magnetic field strength is 8000 A/m, and a residual magnetic flux density Br of 0.5 T or more as measured at that time, and optionally, a coercivity Hc of 100 A/m or more as measured after magnetization reaches 8000 A/m. By using the steel sheet manufactured according to the present invention for a rotor core of an IPM motor, it is possible to increase further an output torque in a high-speed rotational range and raise further the maximum rotational speed.

Disclosed are a hairpin connecting device and a hairpin winding motor including the same. An exemplary embodiment of the present invention may provide a hairpin connecting device including: a cover part shaped like a circular loop fastened to a leg side of a stator core; and a plurality of connection caps arranged inside the cover part in a circumference direction and configured to electrically connect connected ends of respective hairpins exposed to the leg side.

A method for reworking a defective welded connection of a hairpin winding for a rotor or stator of an electrical machine, including providing the hairpin winding applied to a winding support. The hairpin winding has at least one conductor formed from multiple conductor sections. The conductor sections of the respective conductor are welded in pairs at a respective welded connection by a first welding method, and at least one of the welded connections is a defective welded connection. The defective welded connection is severed, and the conductor sections to be welded, which were previously connected by the defective welded connection, are connected by way of a connecting method that differs from the first welding method.

A method for sealing fluid cooled conduits in-situ for a generator is provided. The fluid or liquid cooled conduits are located external to a stator of the generator and substantially outward of stator bars. The method includes draining coolant from the fluid cooled conduits, and drying interior surfaces of the fluid cooled conduits. In inserting step inserts a borescope and a sealant applicator through an opening in one of the fluid cooled conduits. A locating step locates a brazed joint in the fluid cooled conduit, and a positioning step positions the borescope and the sealant applicator near the brazed joint. An applying step applies a sealant to the inside of the fluid cooled conduit at the brazed joint A viewing step may be used to view the brazed joint with the borescope to confirm that the applying step has been successful.
