摘要： A rotor assembly (96) comprises a rotor core (100) comprising a first end (102) and an opposing second end (104), and an outwardly facing peripheral surface (230) having a set of rotor teeth (125) projecting outwardly therefrom to define a set of rotor slots (108) therebetween. Each rotor tooth (125) can comprise a first rotor tooth wall (124), an opposing second rotor tooth wall (126), and a distal tip (125a) between the first rotor tooth wall (124) and second rotor tooth wall (126). Each respective rotor slot (108) can be defined by a respective first wall of a first rotor tooth (125), and a respective second wall of a second rotor tooth (125), and includes a first rotor core conduit (500) extending axially along a length of the first rotor tooth (125). The first rotor core conduit (500) can comprise a first rotor core conduit inlet (506) at the rotor core first end (102) and a first rotor core conduit inlet (507) at the rotor core second end (104), the rotor core conduit (500) defining a first taper (T1) that is narrower at the first rotor core conduit inlet (506) with respect to the first rotor core conduit outlet (507).
