Special frequency changer takes the control theory of the advanced technology as the foundation. The start, acceleration, brake curves are designed according to the ergonomic theory in order to get the finest coziness. It is a genuine current vector control variable frequency drive system.

The permanent magnetic synchronous drive saves up to 50% in energy consumption. VVVF drive ensures operation more smoothly. Nice noise control brings passenger peaceful riding experience.

Highly integrated 32 bit micro networking control system ensures faster data processing time and enhanced functionality. The speed control system is developed based on distance control and high precision elevator car positioning detection technology for efficient operation and accurate car leveling.

Advanced VVVF variable voltage and variable frequency control technology is applied to the elevator door operator system to ensure smooth and quiet switching. The self-learning door load detector monitors the variation of door load on every floor, automatically rectifying the speed for security and reliability.

Rare earth material combined with coaxial transmission technology and digital variable frequency technology. Compared with traditional technology, gearless traction machine can save more than 50% of the energy. It requires no renewal of lubricant, ensuring no grease pollution and low noise levels.
