Publication number: 20200109754Abstract: 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: ApplicationFiled: May 31, 2018Publication date: April 9, 2020Applicant: GENESIS ROBOTICS AND MOTION TECHNOLOGIES CANADA, ULCInventors: James Brent KLASSEN, Damian SPASOV, Christopher ESTERER

Publication number: 20190326834Abstract: A power conversion device has a buckled wave disk that has an axis and is radially compressed between a hub and a wave ring. The buckled wave disk is buckled in the radial direction to form circumferential waves which are displaced in the axial direction and extending around the buckled wave disk with lines formed of inflection points of the circumferential waves extending between the hub and wave ring. The wave ring is outwardly radially displaced at nodes corresponding to lines formed of inflection points of the circumferential waves. A wave propagation actuator cooperates with the buckled wave disk for driving a wave and the lines formed of inflection points of the circumferential waves around the buckled wave disk.

Publication number: 20190288587Abstract: An actuator for high rotational speed applications using a stator which utilizes laminated features to reduce Eddy current losses in the stator. This construction allows high pole counts while providing the efficiency and high speed benefits of a laminated construction. Laminated construction is very challenging for a high pole count lightweight motor, but embodiments of the device provide structural strength, and rigidity, as well as other benefits such as low manufacturing cost, high heat dissipation, integrated cooling channels, and light weight construction. Many of these benefits result from the use of a laminate sandwich of non-magnetic, heat conductive material, such as anodized aluminum, as a structural member of the stator.Type: ApplicationFiled: July 14, 2017Publication date: September 19, 2019Applicant: GENESIS ROBOTICS AND MOTION TECHNOLOGIES CANADA, ULCInventors: James Brent Klassen, Bradley Christopher Pope

Patent number: 10369071Abstract: An exoskeleton suit allows a user to control the legs using the arms. Preferably, there is two-way feedback/control between the legs and arms causing movement of leg joints to be proportional to movement of arm joints.
