Abstract
A motor for use with an elevator system may include a housing, a motor shaft surrounded by the housing and having at least a first end extending outward from the housing, a motor body arranged around a central portion of the motor shaft and positioned within the housing, at least one sheave positioned at the first end of the motor shaft and rotatable with the motor shaft, and a braking system positioned at a first end of the housing. The braking system may include a brake rotor connected to and rotatable with the motor shaft and closing an axial opening at the first end of the housing, a brake shoe positioned at the first end of the housing, and a brake actuator configured to selectively move the brake shoe between a brake position in which the brake shoe is in contact with the brake rotor to resist rotation of the motor shaft and a rotation position in which the brake shoe is free from contact with the brake rotor.
