Title:
ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/102950
Kind Code:
A1
Abstract:
A rotating electrical machine having a stator (60) and a rotor (50), wherein stator teeth that constitute the stator (60) are provided with a core (31), a wire (33) arranged around the core (31), and an insulator arranged between the core (31) and the wire (33), and the core (31) is configured by laminating rectangular thin plates made of a thin plate-shaped amorphous metal material formed to have different widths for each plate or each group of multiple plates. The rotor (50) arranged at both sides of the stator (60) on both sides in the rotary shaft direction is provided with ferrite magnets (20) facing the stator teeth, and a wire (33) uses aluminum as a base material. Such a configuration allows for a rotating electrical machine including a core which can be manufactured with little iron loss at high efficiency and low costs without requiring the deformation and bonding of the core material.
