Renewable energy based elevator system by using BLDC motor: A review

Author(s): Tarte Shital Ramdas
Abstract: Recently, several measures are being taken to conserve energy without degradation in performance. To achieve notable energy savings in elevator systems, in this paper we develop and experimentally test and Operation of an elevator can be classified into four quadrant operation. Four quadrant operation of the proposed elevator system has also been indicated with the simulation results. To demonstrate the successful working of the proposal, a prototype elevator system has been designed and developed in the laboratory. Experiments have been conducted for the upward and downward movement of the elevator cabin with and without load. Brushless Direct Current (BLDC) motors have secured a very significant space in the modern drives industry primarily due to the added benefits of a dc input system along with a brushless drive. Various advantages such as, high torque/current ratio, high power density and higher efficiency make these motors very suitable for replacing conventional motors in many systems. cite such advantages of a BLDC motor and also present a new simulation model that can be used for analysis and design of BLDC motors. Many studies have also been carried out to obtain higher efficiency and better control for BLDC motors. Further, owing to the ease of control and scope for regenerative braking, considerable amount of research has been carried out to incorporate BLDC motors in Electric Vehicles (EVs). This prototype model consists of (i) mechanical components, such as worm gear, pulley and EC, etc., (ii) set of sensors for detecting floor position and rotor position of the motor, (iii) user command buttons, (iv) LED indicators and (v) BLDC motor along with power and control circuits.
