The invention discloses an elevator. The elevator comprises a hoistway, a lift car, a linear motor and a Hall sensor. The lift car is a cuboid and located in the hoistway, and the lift car is slidably connected with the inner wall of the hoistway. Each linear motor comprises a primary module and a secondary module, the primary modules are installed on the lift car, the secondary modules are installed on the hoistway, each secondary module comprises a steel plate and an aluminum plate, the steel plates are connected to the side portions of the hoistway, a plurality of protruding strips are arranged on the steel plates, and the protruding strips are arranged at intervals from the bottom of the hoistway to the top of the hoistway. The aluminum plate is installed on the steel plate, a plurality of through grooves are formed in the aluminum plate, and each protruding strip is located in the corresponding through groove. The Hall sensor is arranged on the lift car. The hall sensor is matched with the grating type secondary module to detect the running speed of the lift car, the running condition of the lift car is obtained by sensing changes of magnetic fields on the protruding strips, and good running of an elevator can be guaranteed by matching with the emergency stop device and the control module.
本发明公开了一种电梯,该电梯包括井道、轿厢、直线电机和霍尔传感器。轿厢为长方体且位于井道内,轿厢与井道内壁可滑动连接。直线电机分别包括初级模块和次级模块,初级模块安装于轿厢上,次级模块安装于井道上,且次级模块包括钢板和铝板,钢板连接于井道的侧部从,所述钢板上设有多个凸条,多个凸条从井道底部至顶部间隔排列。铝板安装于钢板且铝板上设有多个贯通槽,每个凸条位于每个贯通槽内。霍尔传感器设置于轿厢上。本发明采用霍尔传感器配合格栅式次级模块检测轿厢的运行速度,通过感应凸条上磁场的变化从而得出轿厢的运行情况,再配合急停装置和控制模块,可以保证电梯良好运行。
