ROTATING ELECTRICAL MACHINE

摘要

An outer rotor (30) configures an inductive magnetic pole row arranged between a stator and an inner rotor and is provided with a cylindrical rotor core (40) and with first flanges (31) and second flanges (32) on both sides of said cylindrical rotor core. The rotor core (40) is configured from a laminate body comprising integral annular electromagnetic steel sheets laminated in the axial direction. The rotor core (40) is provided with multiple magnetic parts (41) which, spaced at a constant pitch in the circumferential direction, extend in the axial direction and each of which configures an inductive magnetic pole; the rotor core (40) is also provided with multiple connection parts (43) which connect adjacent magnetic parts (41). The adjacent magnetic parts (41) and the connection parts (43) define substantially trapezoidal spaces (42) configuring non-magnetic parts.
