Abstract: The present invention relates to salient pole rotor for an electrical machine, e.g., a motor or generator. The rotor comprises a plurality of salient poles 1, each pole having a pole body 5 and an integral pole tip 4. The rotor further comprises a rotor winding with a plurality of coils, each coil having a plurality of turns and being positioned on the pole body 2 of a respective salient pole 1. Each pole body 2 includes a coil winding part 2A having an outer profile around which the turns of the respective coil are wound in-situ. Each turn includes two substantially straight axially-extending sides and an inner profile that differs from the outer profile of the coil winding part 2A.

Abstract: Provided is a control method and a control system for controlling the insertion of a plurality of magnets within an electrical machine including a stator and a rotor which rotates in relation to the stator around a rotary axis, the control system has plurality of sensors which continuously sense an air gap between the rotor and the stator, an encoder which continuously detects an angular position of the rotor, and a processor which receives data from the sensors and the encoder and determines in real-time an insertion order for inserting the plurality of magnets in a surface of the rotor and applies a feedback loop while performing the insertion process to adjust the insertion order based on changes in the data received.
