Elevator industry is a special industry, Elevator design, manufacture, installation and use have a detailed national standards.The main part of the Elevator has civil, mechanical and electrical and other componentsThe mechanical portion has rail car, counterweight, wire rope and other mechanical parts.Electrical portion has main control board, inverter, traction machine and other components.The operation of the elevator control inverter in the main control board of instruction, driven by the inverter traction machine drives the car running.Inverter as the core component of the elevator system, the safe and reliable operation of the elevator is very important.At the same time, the system also has some special requirements for frequency converter.Many companies for the special requirements of the elevator, the elevator inverter launched to meet the special requirements of the elevator.And Siemens general multifunctional inverter used with modern advanced technical level of insulation gate bipolar transistor (IGBT) as the power output device, with high operational reliability and functional diversity, the pulse frequency optional special pulse width modulation technology, the traction machine with low noise operation, the system is more stable.Comprehensive and perfect protection function provides the system with reliable and good protection performance, high performance vector control technology, a variety of control methods are flexible, suitable for different areas.In the elevator control system, using closed-loop vector control. With fast dynamic response characteristics and superior overload ability.
According to the speed of the elevator, the elevator traction ratio and load to determine the speed and power of traction machine,When determining the power and voltage of traction machine, type selection of frequency converter and traction machine you want to match, usually for selecting more than traction machine power on a class of data.It cannot be small also cannot too big, too big not only causes the cost the rise, moreover causes the control precision to reduce. Make the performance of the whole system drop.
