The invention discloses a linear motor and an electromagnetic suspension, the linear motor comprises a guide column, a central column and a bearing, and the guide column extends along a first direction; the center column sleeves the periphery of the guide column; the bearing is arranged between the guide column and the central column, and the central column slides relative to the guide column in the first direction through the bearing; the linear motor meets the relational expression that H2 = H4-n (H1 + H3), n is larger than or equal to 0 and smaller than or equal to 1.3, H1 is the forward motion stroke of the guide column in the first direction, H2 is the length of the bearing, H3 is the reverse motion stroke of the guide column in the first direction, and H4 is the length of the guide column. The bearing in the linear motor meets the relational expression so as to solve the problems of guiding failure and poor heat dissipation in the motor.

    一种直线电机和电磁悬架,直线电机包括导向柱、中心柱和轴承,其中,导向柱沿第一方向延伸;中心柱套设在导向柱的外周;轴承设置在导向柱和中心柱之间,中心柱通过轴承与导向柱在第一方向上相对滑动;直线电机满足关系式:H2=H4‑n(H1+H3),0≤n≤1.3,其中,H1为导向柱在第一方向上正向的运动行程,H2为轴承的长度,H3为导向柱在第一方向上反向的运动行程,H4为导向柱的长度。该直线电机中的轴承满足上述关系式,以解决电机中导向失效和散热差的问题。
