Mechatronics for elevator installers and drive technicians - REGENERATIVE BRAKING IN LIFTS - WHEN IS IT REALLY WORTHWHILE?

摘要

This report presumes that the reader will be basically familiar with the calculations for lifting and braking power, In earlier reports (see Lift-Report 2/2001 and 3/2001) we discussed in detail the energy situation and the power drawn by elevator lifting machinery, The highly topical subject of "building management" has lent further weight to energy consumption concerns, Is regenerative braking economical and profitable? What advantages and disadvantages will be encountered where such a system is employed in lifts?
