Manufacturing and Engineering Origin

Suzhou Dongao Home Elevator Co., Ltd. operates a 17,000 square meter specialized manufacturing facility in Qidu, the core of China's elevator industry cluster. As a factory specializing in custom industrial traction lifts, we have integrated German-standard PMSM assembly protocols to serve over 5,000 high-end villa projects globally. Our engineering team focuses on the synchronization between the PMSM drive and the cabin frame to ensure that vibrations are dampened at the source. By utilizing a gearless design, we assist residence owners and developers in achieving modern energy standards while maintaining the structural integrity of the private residence. Our facility houses advanced CNC machining centers and automated winding machines to ensure every PMSM unit meets rigorous static load and dynamic balance requirements before shipment to the installation site.

High-Precision Application Environments

• Luxury multi-story villas where machine room noise must be isolated from living areas, typically maintaining levels under 48dB.
• Green-building certified projects (LEED/BREEAM) that require power regeneration and low standby energy consumption.
• High-frequency residential use where traditional geared oil-filled machines would present a maintenance and fire risk.
• Limited-space renovations where the compact footprint of a gearless PMSM allows for more cabin interior space within a fixed shaft dimension.
• Smart homes where the elevator drive must interface with home automation systems for energy monitoring and remote diagnostics.
