This paper describes the characteristics of the 2-pole linear synchronous motor with concentrated magnet arrangement, which consists of two-layer magnet arrays. The upper layer is a main pole composed of two normal excited magnets. The lower layer is composed of three tangentially excited magnets in which the same polarity faces each other. A 3-D boundary integral equation method is applied to the...
This paper describes the thrust and the airgap flux distribution of 2-pole PM linear synchronous motor, The feature of a Halbach array is discussed by comparing with two different type magnet arrangements. One is a conventional magnet arrangement. The other is composed of a Halbach array with a back yoke. 3-D boundary integral equation method is applied to these models. The thrust and the flux density...
Flux concentration in the airgap may attain by adding a Halbach magnet array on the surface of the main magnetic pole of a 2-pole permanent magnet linear synchronous motor (PMLSM). Thrust characteristics significantly change depending on the amount of flux concentration. In this paper, the thrust characteristics by changing the magnet width of normal component in a Halbach array are calculated using...
This paper presents 3D analysis of a permanent magnet linear synchronous motor (PMLSM), where a neodium magnet is used as an excitation magnet. It produces the high power density, and the high thrust more than a self-weight can be attained. In this motor, 3-phase coil arrangement is divided into two rows in transverse direction. A 3D boundary integral equation method is applied to models to calculate...
