Traction|XIZI UHC

From 1999 to 2001 through long-term cooperation and frequent exchanges, the company and Shanghai Jiaotong University gradually achieved mature technology and worked together to develop a gearless traction machine having proprietary intellectual property rights. Up till now, the research and development of this technology is still representing the trend of future development of the elevator industry. Machines using this technology do not need excitation and have small starting currents but extremely high transmission efficiency and more reasonable structures. Compared with traditional traction machines, they have higher efficiency, lower noise, and better environmental and energy-saving performance. They significantly reduce the cost by saving up to more than 30% of energy. Particularly, after the transmission mechanism is removed, the structure of the machine is lighter, smaller, and more compact. It can be directly installed in the shaft to minimize the building area and cost.

For Genral Elevators

In-house made high-performance NdFeB magnet is adopted

The magnets are double fixed and imported thermal switches are furnished, all of which ensure the reliability of the machine performance.

Unique rotating shaft and external rotor construction brings smooth operation of the machine and low noise level.

Ultra-Thin Traction Machine

Applicable for rail mounting.

Super-quiet & easily-adjustable brakes used, make the work-site maintenance and adjustment an easy job.

Improved shaft rotating mode better fitting the working condition of the bearings, bring longer life span.

Wide range of adoptable encoders, both rear-mounted and side-mounted modes available for encoder mounting(compatible with current inverters).

Bar-Shaped Machine

ZZD Brakes adopted, swift in response and reliable in braking. CE approved, excellent quality is ensured.

In-house made heat-resisting NdFeB magnet is adopted to insure the reliability and stability. Thermal switch is furnished to make sure that the demagnetization will never occur.
