The invention provides a secondary assembly for a linear motor, the linear motor, an electromagnetic suspension and a vehicle, and the secondary assembly comprises a first permanent magnet, and the magnetizing direction of the first permanent magnet is parallel to the first direction; the permanent magnet fixing plate is provided with a permanent magnet mounting surface, and the first permanent magnet is arranged on the permanent magnet mounting surface; the first permanent magnet comprises a first end face, a second end face and a first connecting face, the first end face and the second end face are sequentially arranged at intervals in the first direction, the first connecting face is arranged on the side away from the permanent magnet installation face, and the first permanent magnet further comprises a second connecting face which is arranged on the side close to the permanent magnet installation face. According to the scheme, the first connecting surface and the second connecting surface can be respectively arranged on the first permanent magnet, so that an easy demagnetization area of the permanent magnet is effectively removed, the irreversible demagnetization risk of the permanent magnet is reduced, and the thrust fluctuation of the linear motor is further reduced.
本申请提供一种直线电机用次级组件、直线电机、电磁悬架和车辆,包括:第一永磁体,第一永磁体的充磁方向与第一方向平行;永磁体固定板,永磁体固定板具有永磁体安装面,第一永磁体设置于永磁体安装面上;第一永磁体包括沿第一方向依次间隔设置的第一端面和第二端面,以及第一连接面,第一连接面设置于远离永磁体安装面的一侧,第一永磁体还包括第二连接面,第二连接面设置于靠近永磁体安装面的一侧。该方案能够在第一永磁体上分别设置第一连接面和第二连接面,有效去除了永磁体的易退磁区域,降低了永磁体的不可逆退磁风险,进而降低了直线电机的推力波动。
