An e-machine that provides propulsion and regenerative braking includes a rotor and a stator that includes pin conductors encircling the stator. Current is conducted around the stator for a plurality of phases of alternating current. Phase terminals and neutral terminals are connected by terminal connectors to a plurality of wires that connect to the neutral terminal or connect the phase terminals to a source of alternating current. The terminal contacts include means for dampening vibration disposed adjacent terminals. The means for dampening vibration may include a spiral segment of the wire that encircles the terminal or the spiral segment may be disposed adjacent the terminal. A flexible joint assembly may be a clamp including a terminal contact that is movable on ball bearings between an upper jaw and a lower jaw. Another flexible joint assembly may include a receptacle that receives a plug supported on ball bearings.
