Title:
STATOR CORE FOR ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/097908
Kind Code:
A1
Abstract:
The purpose of the present invention is, when forming a stator core of a rotating electrical machine by laminating and fixing a plurality of core plates, to suppress torque fluctuation by setting a fixing portion based on a relative positional relationship with the magnetic pole of a rotor. The relationship among the number of rotational buildup states which is a value calculated by dividing 360 degrees by the rotational buildup angle (θs) by which the core plates are circumferentially rotated for each prescribed lamination number, the number of magnetic poles that is a number of magnetic poles (M) of the rotor and the number of fixing portions that is a number of fixing portions (5) is set such that the number of the fixing portions is an integer multiple of the number of rotational buildup states, while the common divisor for the number of the fixing portions and the number of the magnetic poles is at least only "1" or only "1" and "2".
