    摘要: Disclosed are a high-damping and high-thrust cylindrical linear motor and a motor-driven power steering device. A stator includes three-phase stator and a stator core. A slider includes a slider core and permanent magnets. The stator core includes stator-core salient poles, two auxiliary poles and yoke units with a small poles on its surface of the side of the slider, the auxiliary poles being deployed at both ends of the stator-core salient poles, the yoke units configuring a magnetic circuit in cooperation with the stator core and the auxiliary poles. The magnetic circuit is shared among the three phases. Polarities of magnets of the slider become an identical polarity, each of the plurality of permanent magnets being positioned at a position which is opposed to each of the plurality of small poles included in one stator-core salient pole out of the plurality of stator-core salient poles.
