Title:
ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/113935
Kind Code:
A1
Abstract:
An electric motor (400) comprises: a rotor (410) having a plurality of magnetic poles; a stator (430) having a multiphase stator winding (431); a power line (485) which supplies power to the stator winding; and a rotation sensor (520) which detects a rotary position of the rotor, wherein the stator and the rotor are disposed facing each other inside and outside in a radial direction. Signal lines (522) which extend from the power line and the rotation sensor are provided so as to extend in axial directions, and shielding sections (401, 473) which shield a magnetic field produced by the power line are interposed between the power line and the signal line.
