Title:
BIAXIAL-INTEGRATED TYPE MOTOR
Document Type and Number:
Japanese Patent JP2018201299
Kind Code:
A
Abstract:
To provide a biaxial-integrated type motor which easily improves detection accuracy of a detection part that detects a rotational angle of a rotor.SOLUTION: A biaxial-integrated type motor comprises: a detection part that includes a first detection part for detecting an absolute angle of an outside rotor and a second detection part for detecting an absolute angle of an inside rotor; a bearing part that includes a first bearing for rotating in linking with the outside rotor and a second bearing for rotating in linking with the inside rotor; a stator core part that includes a stator core of the outside rotor and a stator core of the inside rotor; and a base to which those parts are attached. A first rotator 100 of the first detection part (and a second rotator 101 of the second detection part) are arranged in a concentric ring-state so that a pair of pole logarithms 2A1 and 2B1 (2C1 and 2D1) is at equal intervals, and includes a plurality of magnetic tracks which have a different number of the pair of pole logarithms each other.SELECTED DRAWING: Figure 4
