Patent number: 11411460Abstract: An electric machine assembly including a terminal assembly and three terminal lugs is provided. The terminal assembly may include three pairs of terminal leads. Each of the three terminal luges may define a pair of terminal lead through-holes and a pair of opposing radial sides. Each terminal lug may be compressed at one of the sides to deform a respective terminal lug and secure each of the pair of terminal leads within one of the pair of terminal lead through-holes. The assembly may further include a stator disposed within a housing and include end windings. Each of the terminal leads may include a base terminal portion. The terminal assembly and the stator may be arranged with one another such that each base terminal portion is aligned with one of the end windings for securing thereto. The assembly may further include three bridges.Type: GrantFiled: January 8, 2019Date of Patent: August 9, 2022Assignee: Ford Global Technologies, LLCInventor: Casey Taylor Dunn

Patent number: 11283323Abstract: A stator of an electric machine has first and second hairpin winding terminals connected with a first electrical phase and extending axially away from end windings of the stator. A hairpin winding of a second electrical phase is located circumferentially between the first-phase terminals and spaces them from one another. A jumper has spaced-apart C-hooks oriented face-to-face relative to one another and wrapping around respective exposed ends of the first-phase hairpin winding terminals. The jumper forms a bridge spanning between the first-phase hairpin winding terminals and over the second-phase hairpin winding terminal. During manufacturing of the stator, the C-hooks are slid axially downward onto respective non-insulated ends of the first-phase stator hairpin winding terminals. The C-hooks abut against and are axially positioned relative to the first-phase terminals by ledges defined by insulative coatings that cover portions of the first-phase hairpin winding terminals.Type: GrantFiled: February 28, 2019Date of Patent: March 22, 2022Assignee: Ford Global Technologies, LLCInventor: Casey Taylor Dunn
