Abstract
An elevator machine (10) includes a machine shaft (14, 14′) and a sheave (26) that rotates with the machine shaft (14, 14′). A motor (12) selectively rotates the machine shaft (14, 14′). A brake (30) having at least one brake armature (36) selectively moves a brake rotor (28) coupled for rotation with the shaft (14, 14′) between a braking position and a released position. The brake rotor (28) selectively contacts a braking surface (44) formed directly on a housing (20, 22, 84, 90) to resist rotation of the machine shaft (14, 14′).
