The purpose of the present disclosure is to obtain an electromagnetic brake device and an elevator hoist that can suppress impact when a movable iron core collides with a fixed iron core without large-scale modification. The movable iron core (32) is provided with an iron core main body (44), a pair of divided iron core pieces (45) and a displacement mechanism (46). Each of the divided iron core pieces (45) is displaceable between an approaching position and a separating position. The displacement mechanism (46) makes the divided iron core pieces (45) close to each other when the iron core main body (44) is located at the first position, and makes the divided iron core pieces (45) far away from each other when the iron core main body (44) is located at the second position.

    本公开的目的在于得到电磁制动装置以及电梯曳引机,其不需要大规模的改造就能够抑制可动铁芯与固定铁芯碰撞时的冲击。可动铁芯(32)具有铁芯主体(44)、一对分割铁芯片(45)以及移位机构(46)。各分割铁芯片(45)能够在接近位置与远离位置之间移位。移位机构(46)在铁芯主体(44)位于第一位置时使各分割铁芯片(45)位于接近位置,在铁芯主体(44)位于第二位置时使各分割铁芯片(45)位于远离位置。
