Publication number: 20240120791Abstract: A permanent magnet carrier, which could be a rotor or stator of an electric machine, includes a first non-magnetic ring and a second non-magnetic ring. Between the rings are soft magnetic pole elements. The soft magnetic pole elements each connect to the first and second non-magnetic rings and the soft magnetic pole elements are separated from each other by the first and second non-magnetic rings. Permanent magnets are disposed between the soft magnetic pole elements.Type: ApplicationFiled: October 16, 2023Publication date: April 11, 2024Inventors: James Klassen, Damian Spasov, Bradley Pope, Jason Kum

Patent number: 11187293Abstract: A magnetic brake for a motor uses the magnetic force on the surface of a flux concentrating rotor to pull a flexible brake spring or friction sheet into friction contact with the rotor. An electromagnetic stator pulls the flexible brake spring or friction sheet away from the rotor when it is energized. The brake spring may be a variable thickness around the circumference in a radial flux motor or radially in an axial flux motor and is thicker near where it is fixed to the housing. The brake spring may be split so it can clamp down on the rotor symmetrically. The OD of the brake spring may be closer to the surrounding stator near the fixed section of the brake spring so the air gap to the brake stator is smaller and the gap to the rotor and the ID of the brake spring is larger to allow the brake stator to pull on this area with greater force initially when it is energized to disengage the brake.Type: GrantFiled: May 31, 2018Date of Patent: November 30, 2021Assignee: GENESIS ROBOTICS AND MOTION TECHNOLOGIES CANADA, ULCInventors: James Brent Klassen, Damian Spasov, Christopher Esterer

Patent number: 11128188Abstract: An electric motor has a first carrier having an array of electromagnetic elements and a second carrier having electromagnetic elements defining magnetic poles. The first and second carriers each define an axis. An airgap is formed between the first and second carriers when in an operational position. An inner thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. An outer thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. The electromagnetic elements of each of the first and second carriers are arranged radially inward of the outer thrust bearing and radially outward of the inner thrust bearing. The inner thrust bearing and the outer thrust bearing are arranged to maintain the airgap against a magnetic attraction of the electromagnetic elements of the first and second carriers.Type: GrantFiled: September 18, 2019Date of Patent: September 21, 2021Assignee: GENESIS ROBOTICS AND MOTION TECHNOLOGIES CANADA, ULCInventors: James Brent Klassen, Damian Spasov, Bradley Pope
