Title: Bertil Larsson: Innovator in Electrical Engineering

Introduction

Bertil Larsson is a notable inventor based in Vasteras, Sweden. He has made significant contributions to the field of electrical engineering, particularly in the design and functionality of rotating electrical machines. With a total of 5 patents to his name, Larsson's work showcases his innovative approach to engineering challenges.

Latest Patents

One of Larsson's latest patents is for a rotor disk with spoke openings. This rotor disk is designed for a synchronous reluctance machine and consists of a disk body made from a material with high magnetic permeability. To enhance the rotor disk's ability to withstand centrifugal and thermal loads, spokes extending radially between a shaft opening and the disk periphery are equipped with spoke openings. These openings are strategically placed to reduce the heat conducting properties of the spokes and to make them less stiff.

Another significant patent by Larsson is a method of applying a tube member in a stator slot in a rotating electrical machine. This method involves mounting a tube in a space that corresponds to its shape. The tube is inserted into the space and pressurized with a hot pressure medium, causing it to expand until the space is filled. Subsequently, a cold pressure medium is used to replace the hot pressure medium while maintaining constant pressure, allowing the tube to solidify in its expanded shape. This innovation also includes a rotating electric machine that features such a tube between the windings of a high-voltage cable in a stator slot.
