Patent number: 11967873Abstract: A fractional slot electric motor includes a stator core having a first side, a second side, and stator slots extending between the first and second sides. The fractional slot electric motor also includes a coil having a plurality of coil elements, where each coil element extends through at least one of the stator slots. Each coil element is coupled to at least one other coil element along the first side of the stator core. A first subset of the coil elements includes coil elements coupled to each other along the second side of the stator core. A second subset of the coil elements includes loop coil elements, where each loop coil element extends from one of the stator slots to another of the stator slots along the second side of the stator core without being connected to other coil elements along the second side of the stator core.Type: GrantFiled: May 5, 2023Date of Patent: April 23, 2024Assignee: Canoo Technologies Inc.Inventors: James Dameron, Evan Filter, Phillip Weicker, Charles Garmel

Patent number: 11949306Abstract: Described herein are fractional-slot-winding motors and electric vehicles using such fractional-slot-winding motors. In some examples, a fractional-slot-winding motor comprises a stator, a bus-bar assembly, and a plurality of coil units. The stator comprises a plurality of stator slots (e.g., 63 slots) extending through the core and radially offset relative to each other. Each dual-leg coil unit extends through two different stator slots and is electrically coupled to two other coil units on the coil-interconnection side of the rotor. Each single-leg coil unit extends through one coil slot and is electrically coupled to one other coil unit on the coil-interconnection side. At least some single-leg coil units can be coupled to a bus-bar assembly. Furthermore, the ends of the coil unit can have radial offsets relative to protruding portions, e.g., closer to the motor primary axis at the coil-interconnection side and further away on the opposite side.Type: GrantFiled: September 6, 2023Date of Patent: April 2, 2024Assignee: Harbinger Motors Inc.Inventors: Jackson George Diebel, Alex Tylee, James Dameron, Phillip John Weicker

Publication number: 20230341043Abstract: A lower sump is disposed at a bottom of a housing for an electric motor/stator and drive train of an electric vehicle. The lower sump is configured to accumulate coolant/lubricant fluid that has passed through windings of the electric motor/stator. The lower sump includes a portion configured to receive part of one or more drive gears for the drive train. An upper sump is disposed above the electric motor/stator and drive train and is configured to accumulate at least a portion of the fluid that has been moved by the drive gear(s). One or more electronically-controlled exit or entrance valves are configured to be positioned between the upper sump and one or more spaces adjacent to the windings. The one or more exit or entrance valves are configured to release the fluid from the upper sump to flow through the space(s) adjacent to the windings into the lower sump.Type: ApplicationFiled: April 22, 2022Publication date: October 26, 2023Inventors: Charles Garmel, James Dameron, John Mason (deceased), Yufei Zhu

Patent number: 11646623Abstract: Described herein are fractional slot electric motors with compact crowns. A motor comprises multiple coil elements protruding through a stator core and forming electrical connections with each other and/or with a lead assembly. The lead assembly comprises phase busbars connected to selected coil elements and comprising terminals for connecting to an external power supply. The lead assembly also comprises neutral busbars, with no external connections and internally connected to other coil elements. Each coil element has a rectangular cross-sectional profile to maximize the slot-fill-ratio of the motor. Each coil element is electrically coupled to two other components. For example, each looped coil element is coupled to two other coil elements at a stator side, opposite the lead assembly. Each extended coil element is coupled to another coil element at that same side and coupled to another coil element or a busbar at the lead assembly side.Type: GrantFiled: May 28, 2021Date of Patent: May 9, 2023Assignee: Canoo Technologies Inc.Inventors: James Dameron, Evan Filter, Phillip Weicker, Charles Garmel
