Linear motors (10) and elevators (100) are presented in this document. A linear motor (10) comprises a stator (20) and a mover (15) adapted to move along the stator (20), one of them (20, 15) comprising non-magnetic core coils (25) arranged in a row (24) in a longitudinal direction (Z). Further, the other of the stator (20) and the mover (15) comprises permanent magnets (28) arranged in at least two adjacent rows (27) in a longitudinal direction (Z), wherein the rows of permanent magnets (27) are separated by a gap(s) dimensioned for receiving the row(s) of coils (24). Still further, at leastone of the rows of permanent magnets (27) may be arranged in a form of Halbach array (40). The elevator (100) may comprise an elevator shaft (30) and an elevator car (5) arranged to be moved by the linear motor (10) in the elevator shaft (30).
在本文中介绍线性电动机(10)和电梯(100)。线性电动机(10)包括定子(20)和适于沿定子(20)移动的动子(15),其中一个(20、15)包括沿纵向方向(Z)成排(24)布置的非磁芯线圈(25)。此外,定子(20)和动子(15)中的另一个包括在纵向方向(Z)上布置在至少两个相邻排(27)的永磁体(28)中,其中,永磁体(27)的排隔开一个或多个间隙,间隙尺寸设定为接收线圈(24)的排。更进一步,永磁体(27)的排中的至少一排可以以Halbach阵列(40)的形式布置。电梯(100)可以包括电梯井道(30)和布置成由线性电动机(10)在电梯井道(30)中移动的电梯轿厢(5)。
