1. Project: Siemens helps Jiangsu Xide Make the Best Elevator Client: Jiangsu Xide Elevator Co., Ltd. Industry: MechanicalManufacturing • Challenges • When established in 2010, Jiangsu Xide had difficulty in market expansion, so it needs high-quality products to get market recognition. • As a special apparatus, elevator safety draws great concern, which is determined by the safety and stability of the door-motor system. However, since its frequent movement, , it is hard to keep it safe and a stable and reliable driver is needed. Solutions • The combination of Siemens MM440 general inverter and 1LA7 high-efficiency energy saving motor is used in elevator synchronous car door-motor system, guaranteeing elevator safety and stability. • First cooperation: an order of 2000 sets  • Secondcooperation: an order of 3000 sets • Siemens 5SJ6 small circuit breaker, 3TH80 relay, 3RH11 relay, 3TF contactor, 3RT1 contactor and other low-voltage electrical components are used in the control cabinet. The electrical and mechanical units of Siemens low-voltage electrical components have such advantages as long life, low operation noise and operation temperature up to -25 ℃ - 55 ℃. • Siemens' unique vector control technology, common DC bus inverter, AFE and other core technologies ensure elevators’ quality and improve their competitiveness. Xide Synchronous Car door-motor system • Growing rapidly within three years, Jiangsu Xide has become a technology-driven company with independent R&Dcapacity. • A paragon case of Siemens helping local enterprises grow rapidly Project Highlights: Client's Benefits • Jiangsu Xide has made high-quality, safe and stable products, getting users’ recognition and market expansion. • With Siemens' brand, Xide Elevator has gradually built up its own brand.
