摘要： An electric machine (100) includes a stator and one or more rotor modules (106). Each rotor module (106) includes a rotor hub (108) having a hub body (114), a plurality of first protrusions (116) including an elongated portion (120) and a head portion (122) and a plurality of second protrusions (118) including a wedge-shaped profile with an top portion (122). First and second protrusions alternate on the circumference of the hub body (114). The rotor module (106) includes a magnetic core (110) having a plurality of core members (128) disposed on the rotor hub (108). Each core member (128) is retained by the head portion (122) of the first protrusion (116) and is located between adjacent second protrusions (118) extending at least partially in a space between adjacent core members (128). The rotor module (106) includes a permanent magnet (112) disposed and retained between adjacent core members (128).
