Document Type and Number:
Japanese Patent JP7436266
Kind Code:
B2
Abstract:
To provide a stator which reduce a processing time and suppresses a leakage of a filler, and provide a dynamo-electric motor having the stator.SOLUTION: A stator comprises: a stator core having a nearly cylindrical shaped stator core main part having a predetermined thickness, and a nearly circular-ring shaped stator core sub-part which is provided so as to be connected to an end face of a shaft direction of the stator core main part, and which has an inner diameter larger than that of the stator core main part while having nearly the same outer diameter as that of the stator core main part; a coil which is attached to an inner peripheral side of the stator core main part, and where a coil end part is deviated from an end face in the shaft direction of the stator core main part; an end ring having an end ring main part which has nearly the same outer diameter as the stator core, and surrounds the coil end part by being continued to the stator core in the shaft direction, and an end ring sub-part which is continuously provided to the stator core side in the end ring main part, where the outer diameter is smaller than the end ring main part, and which is arranged in the inner peripheral side of the stator core sub-part ; and a filler which is filled inside of the end ring to cover the coil end part.SELECTED DRAWING: Figure 1
