Large differences are discovered when the energy consumption of different types of lift drive are compared. In general the question is: what is the most energy and cost-saving solution for a lift drive system? Using a special measurement set-up and a computer program to standardise the results, a comparison has been made between single-speed, two-speed, chopper and VVVF drives. The results of the test showed clearly the advantages and disadvantages of the various drive systems.
