Power-off self-locking motor and gate
The invention discloses a power-off self-locking motor and a gate. The power-off self-locking motor comprises a shell, a rotor, a polygonal limiting sheet installed on the rotor and a locking device, wherein the locking device comprises an electromagnetic adsorption piece fixedly connected with the shell, an upper friction sheet movably installed on the electromagnetic adsorption piece, a lower friction sheet located between the upper friction sheet and the electromagnetic adsorption piece, a limiting friction sheet located between the upper friction sheet and the lower friction sheet, and an elastic piece arranged between the lower friction sheet and the electromagnetic adsorption piece, the electromagnetic attraction piece can generate magnetic attraction force on the upper friction sheet and the lower friction sheet, a polygonal limiting hole is formed in the limiting friction sheet, the rotor penetrates through the polygonal limiting hole, and when the polygonal limiting sheet is located in the polygonal limiting hole, the limiting friction sheet can limit rotation of the rotor. Compared with the mode of locking the gate by meshing the upper teeth and the lower teeth, the mode that the polygonal limiting hole in the limiting friction sheet is matched with the polygonal limiting sheet on the rotor has the advantage that the cost of the gate is reduced.
本申请公开了一种断电自锁式电机及闸机。断电自锁式电机，包括壳体、转子、安装于转子上的多边形限位片，以及锁紧装置；锁紧装置包括与壳体固定连接的电磁吸附件、活动安装于电磁吸附件上的上摩擦片、位于上摩擦片与电磁吸附件之间的下摩擦片、位于上摩擦片与下摩擦片之间的限位摩擦片，以及设于下摩擦片与电磁吸附件之间的弹性件；电磁吸附件能够对上摩擦片及下摩擦片产生磁吸力；限位摩擦片上开设有多边形限位孔，转子贯穿多边形限位孔，当多边形限位片位于多边形限位孔内时，限位摩擦片能够限制转子转动。限位摩擦片上的多边形限位孔，与转子上的多边形限位片配合的方式，相对于上下齿啮合，使闸机锁死的方式，降低了闸机的成本。
