March is the month where the Northern hemisphere celebrates spring, rebirth of earth, and new beginnings. Likewise at the end of March, autumn starts in the Southern hemisphere after enjoying a beautiful sunny summer, continuing the cycle of life. In March 2020, however, both hemispheres suffered and are still suffering from the terrible SARS-CoV-2 (COVID-19) pandemic, during which our lives drastically changed and the lives of others took an unexpected turn. Thousands of people have lost their lives, so if you lost someone you loved, I am sorry for your loss. The human race has suffered many pandemics before, and survived. Therefore, we will survive this together, and emerge stronger. At the forefront fighting this pandemic are medical professionals, as well as every person who made sure we all have food, power, water, and other essential needs. We should be thankful for their sacrifice and dedication.
The Eureka of Archimedes in 230 B.C when the pulley was hooked to the top with a wooden box as a cab and pulled by muscular power to the present gearless traction version with steel or glass cab pulled with electrical power emphasizes the elevator architecture came across series of rebirth. Today with the urge of smart and sustainable transportation system the elevator technology is subjected to relentless innovation in the field of control algorithm and the electric motor. The direct current (DC) motors were for years as standard type of elevator motors and with the advancement in drive technology alternating current (AC) motors especially induction motor flourished for past few years, but later with the introduction of permanent magnet synchronous motors (PMSM) technology the elevator revolution began in terms of power quality, ride quality and green energy.
Legislative frameworks are becoming increasingly stringent due to global warming. As a result, there is pressure on the transportation industry to reduce fuel consumption and average CO2 emissions. This has led to a two-pronged approach: development of advanced electric drive propulsion system technologies for vehicle powertrains, and advanced testing methodologies.
