Abstract

Elevator traction motors are critical components of elevator systems. After the structural analysis of the traction motor, it is necessary to proceed to the production processes for the comfortable and safe use of elevator systems. In this study, the static load values for bearing lifetime calculation, belt selection, and finite element analyses (FEA) were determined. According to calculated loads; materials, bearings, belt, pulley, brake, and encoder were selected. In order to obtain a design in accordance with elevator standards, motor parts were examined for structural analysis. Finite element analyses were carried out according to the determined maximum static load values, and a new belt elevator traction motor design that provides the safety coefficients has emerged. When the FEA analysis results of bending moments are examined; the maximum Von Mises stress acting on the motor frame and shaft was obtained 17.1 MPa and 27.62 MPa respectively. The maximum Von Mises stress was obtained under the torsional moment as 71.4 MPa and the shaft is 6.1 times safe against a torsional moment. This value is the minimum safety factor of the designed system and safety factors of bending moments are higher than this value. The designed elevator machine has got 12.9 kW rated power, 1.6 m/s cabin speed, and 1175 kg carrying capacity. The advantage of the proposed design is to eliminate the casting process with modular structure via double side belt system. The prototype of the designed motor was produced and it was observed that the motor provided the desired constraints as a result of the loading experiments.

A Laboratory Machine Verifying the Operation of a Hydraulic Rope Equalizer with Tensometric Sensors

“…According to [1], the load capacity of traction elevators [6][7][8], which are adapted to transport people, is assigned the largest usable area of the cage, in order to prevent overloading of the cage with the number of transported persons. For high load capacities (over 2500 kg) of traction elevators, 0.16 m 2 of area is added (to an area of 5 m 2 ) for every 100 kg increase in weight.…”
