Figure 1 shows the energy-saving benefits of using a reduced-speed mode in an escalator application featuring a 15kW induction motor in various control modes. The largest incremental savings result from using a VFD to operate the motor at a reduced speed during periods of inactivity. Figure 1: Power Consumption ( kW ) of unloaded 15kW Escalator Motor, P : power of motor kW . ST : daily running with people. TP: travel time. Example: Motor power 2.8 kW , speed of the elevator 1m / s, running daily start 100, TP (door open + door close + departure + arrival + time to travel + arrival + door open +door close) is 12 seconds for 360 days. Einv = 0.3 x 2.8 x 100 x 12/3600 = 0.28 kWh / day, LIFT AND ESCALATOR MOTOR SIZING WITH CALCULATIONS & EXAMPLES . Dr. Lutfi Al-Sharif . Published in Lift Report, January/February 1999. … Thus, a 50 kW motor .
