Analysis of Electrical Energy Consumption Due to the Influence of Passenger Weight on the Medan Fair Plaza Elevator
Keywords:
Active Power, Electrical Energy, elevator Motor, ConsumptionAbstract
An elevator is a mechanical device designed to facilitate vertical transportation of people or goods between floors within a building. This system operates automatically through a drive motor and specific control mechanisms, enabling time and energy efficiency in multi-story structures. This study aims to evaluate the extent to which passenger load influences the power and electrical energy consumption of the elevator drive motor at Plaza Medan Fair, particularly when operated at 0%, 50%, and 100% of its maximum load capacity. The method applied in this research involved direct data collection on-site.
Observations revealed that under no-load conditions (0 kg), the power required for upward movement reached 4.62 kW, with a total energy usage of 55.44 kWh over a 12-hour period. At 50% load (approximately 525 kg), the power increased to 7.61 kW, and energy consumption rose to 91.32 kWh. At full load (±1050 kg), the elevator consumed 8.21 kW. During downward movement, the elevator with no load consumed 5.51 kW of power and 66.12 kWh of energy. With a 50% load, the power used was 7.12 kW and energy consumption reached 85.44 kWh. At full capacity during descent, power consumption was recorded at 7.34 kW with 88.08 kWh of energy used.These findings confirm that variations in passenger load significantly affect both the power demand and energy usage of the elevator’s drive motor. Therefore, regular maintenance and performance checks are essential to ensure the lift operates efficiently and reliably.
