电梯曳引机型式试验装置的设计

Design of Type Test Device for Traction Machine of Elevator

将四象限变频电源技术应用于电梯曳引机型式试验台的研制中,实现了电功率闭环的电机对拖负载试验。试验台配备高精度的功率分析仪、JN338-A系列转矩转速传感器和其它仪器仪表,可实现45kW以下三相异步电动机和30kW以下无齿轮永磁同步曳引机的驱动主机型式试验,以及10000N·m以下的制动力矩性能试验。

Applied to the development of elevator machine type test stand with the four quadrant variable frequency power supply technology,the motor-to-load test with closed-loop electric power is realized.The test stand is equipped with high precision power analyzer,JN338-A series torque and rotating speed sensors and other instruments.It can be used to test the machine with threephase asynchronous motor up to 45 kW and gearless permanent magnet synchronous motor below 30 kW,as well as the braking torque below 10000 N.m.
