IMPROVEMENTS ON THE ELECTRIC DRIVE ELEVATOR PROTOTYPE. PART I TECHNICAL ASPECTS

The objective of the paper is to present some improvements done on the previously described electric drive elevator prototype [1]. The modern electric elevator contains both the cabin (replaced at the research laboratory by one trolley), and the counterweight (replaced by the opposite trolley which contains modular weights). Through the appropriate gearbox the connexion between the pulley and electric motors is provided. The designed load of the elevator conducts to the 4kW three-phase squirrel cage driven motor supplied by the power inverter prototype through the chain transmission. The modified experimental platform is depicted and the adequate experimental results are provided.
