PERMANENT MAGNET (PM) BRUSHLESS MACHINE WITH OUTER ROTOR

摘要

An electric machine (10) is provided and includes a stator (20) that includes teeth (22), conductive windings (30) configured to be wound about the teeth (22) and a rotor (40) rotatable about the stator (20). The rotor (40) includes an annular core (43) defining first slots (60) along a circumferential dimension and one or more second slots (70) along the circumferential dimension between neighboring first slots (60), permanent magnets (44) disposable in the first slots (70) and cage windings (45) disposable in the second slots (70).
