Abstract (en)
[origin: EP1790609A1] In a winch for an elevator according to this invention, a brake side housing is arranged in opposition to and fixedly secured to a motor side housing with a motor arranged therein. A sheave is rotatably mounted on a fixed shaft that penetrates through these brake side housing and motor side housing and is fixedly attached thereto. A pair of brake arms have their one ends rotatably mounted on the brake side housing, and brake shoes being in sliding contact with braking surfaces of a brake drum are attached to the brake arms, respectively. Brake springs are arranged in the brake side housing between the pair of brake arms for urging the pair of brake arms in a direction away from each other. An electromagnetic magnet is arranged in the brake side housing between the other ends of the pair of brake arms for attracting the other ends against the resilient forces of the brake springs thereby to rotate the brake arms.
