摘要:
The method for impregnating with a resin (9, 10) an insulating material (3, 5) applied to a conductor (2) comprises supplying the conductor (2) with an intermittent current (12) during impregnation for it to generate a variable magnetic field. The conductor (2) comprises a plurality of transposed strands (4), and/or it is immersed in an external magnetic field, and/or it faces a ferromagnetic element (15).

摘要:
A coupling structure comprising coupling parts and aligners to connect the coupling parts. The aligner comprises a first circular element (1) with a first eccentric hole (6) and is contained in a hole (5) of a first coupling part (2). The structure gives flexibility to assemble the coupling parts and thus reduces the machining and assembling difficulty of the coupling parts.
摘要:
The electric machine (1) comprises a casing (2) that houses a stator (3) and a rotor (4). The stator (3) has cooling channels (5) for a cooling gas. The electric machine also has an end casings (9) connected to at least one casing (2) end. The end casing (9) has channels (10) for the cooling gas. Deflectors (15) to guide the cooling gas between the channels (10) of the stator (3) and the channels (5) of the end casing (9) are provided. The deflectors (15) are separate pieces from the end casing (9). The deflectors (15) are connected between the stator (3) and the end casing (9).
