Abstract: To alleviate the ear block discomfort of passengers without causing any undue reduction in the operational efficiency of an elevator. A travel distance calculating section 13 calculates a travel distance of a car room 1 based on destination floor information 12a and a car position command signal 3a, and output travel distance information 13a to a speed pattern generating section 14. The speed pattern generating section 14 compares the travel distance with a predetermined distance, generates a speed pattern 14a of a normal operation if the travel distance is short, and generates the speed pattern 14a of a partially low speed operation if the travel distance is long. The predetermined distance indicates a difference in height corresponding to a difference in air pressure that causes the Eustachian tube to open against ear block discomfort by a passenger. A speed control section 24 makes the car room 1 move up and down based on the speed pattern 14a.

Abstract: When there is a breakdown in either one of first and second power converters supplying electrical power to a multi-winding motor comprising a wind-up mechanism, a rescue operation can be safely and reliably carried out by using the remaining power converter. A wind-up mechanism comprises a two-winding motor having first and second windings, and, during normal operation, power is supplied to the first and second windings from first and second inverters respectively. When the first inverter has broken down due to excessive current, first and second contactors are switched off, and a third contactor comprising a short-circuiting unit is switched on. Consequently, both windings receive power from the second inverter, enabling the rescue operation to be carried out without causing vibrations.
