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.
