Abstract (en)
[origin: WO2016162128A1] The invention relates to a method for producing a rotor (1) for a synchronous motor (29) which is suitable for a rotational speed of more than 1000 r.p.m. and comprises at least one field coil (2). The at least one field coil (2) has in each case at least two windings (3) which consist of a plurality of parallel electrically conductively connected rectangular sub-conductors (15). In order for the rotor to be produced cost-effectively and to be used at high speeds and at the high centrifugal force loads associated therewith, according to the invention the field coil (2) is produced by a continuous winding and soldering method. In the production method first of all a plurality of parallel rectangular sub-conductors (15) are joined together lengthwise loosely to form an entire conductor (16), then the entire conductor (16) is wound to form a field coil (2) and finally, directly after the winding, the sub-conductors (15) of the entire conductor (16) are soldered together continuously to form a solid field coil (2) with a rigid entire conductor (16).
