Document Type and Number:
Japanese Patent JP2015037366
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamo-electric machine having a simple structure, in which detection accuracy of the rotational position of a rotor is enhanced.SOLUTION: A magnetic detector included in a dynamo-electric machine has a magnetic flux incidence plane provided at a position separated to one side of a crankshaft in the axial direction, from the end face on one side of a crankshaft in the axial direction at a permanent magnet, and from the end face on one side of a crankshaft in the axial direction at a tooth, in a mode of crossing a line parallel with the axial direction of a crankshaft, and detects a magnetic flux radiated from the permanent magnet into a space closer to one side of the crankshaft in the axial direction than the tooth, and impinging on the magnetic flux incidence plane in the axial direction of a crankshaft, from the space closer to one side of the crankshaft in the axial direction than the tooth.
