[0002] The elevator traction machine, also known as the elevator main unit, is the core of an elevator's power system. Its main function is to deliver and transmit power, driving the elevator's operation. It consists of a motor, brake, coupling, gearbox, traction sheave, frame, guide wheels, and an auxiliary handwheel. The guide wheels are typically mounted on the frame or its supporting beams, playing a crucial guiding role. Some handwheels are fixed to the motor shaft for easy emergency operation; others are normally hung on the wall and slipped onto the motor shaft when needed, offering flexibility and practicality.
[0003] There are various types of elevator traction machines available, categorized by reduction method into geared and gearless types. The former uses a reducer for transmission and is used in low- and medium-speed elevators, while the latter is directly driven and suitable for high-speed elevators. In terms of the drive motor, there are DC and AC types. During operation, the motor is energized and transmits power to the traction sheave. The friction between the traction sheave and the wire rope drives the car and counterweight in relative motion, thus raising and lowering the elevator. The brake is used to apply pressure when necessary to ensure safety.
