Summary:An elevator drive apparatus is described which comprises a drive unit (36, 37) for driving an elevator car (32), a brake device (35) for braking a motion of the elevator car (32), a detector (60) fordetecting an electrical operation amount of the drive unit (36, 37), and a controller (50). The controller (50) is configured to release the brake device (35), to compare the detected electrical operation amount with a threshold, and to apply the brake device (35) when the detected electrical operation amount exceeds the threshold. In this way, it is ensured that a speed of the elevator car in case of a rescue situation is within a safety limit. 描述了种电梯驱动设备,包括:驱动单元(36、37),用于驱动电梯轿厢(32),制动装置(35),用于制动所述电梯轿厢(32)的运动,检测器(60),用于检测所述驱动单元(36、37)的电操作量,和控制器(50)。所述控制器(50)配置为:释放所述制动装置(35),将检测到的电操作量与阈值进行比较,以及当检测到的电操作量超过阈值时应用所述制动装置(35)。这样,确保了在救援情况下电梯轿厢的速度在安全限制内。
