FIELD: electricity. ^ SUBSTANCE: reactor unit comprises a winding coil, aluminium wires of which are wound around the iron core. The electric output made of copper is connected to end parts of the winding coil and has a pressed and a connecting part for pressing and connection of the winding coil aluminium wires at one end, and a welded part of an approximately flat shape at the other end, so that an electrical connection between heterogeneous materials is realised at low cost and high reliability. ^ EFFECT: cost reduction and reliability improvement. ^ 3 cl, 5 dwg |
