Limited space creates infinite possibilities

Control System

Using dual 32-bit embedded control processors and drive processors, the control system receives dual safety protection to ensure efficient operation of the elevator. The application of new PWM compensation technology and dynamic PWM carrier modulation technology can effectively reduce motor noise and motor losses. Data network control technology based on CANBUS ensures the reliability and electromagnetic interference resistance of the communication system between the elevator control components.

Permanent magnet synchronous gearless traction machine

It uses rare earth materials, adopts an outer rotor structure, is driven by a permanent magnet synchronous motor, eliminates vortex rod transmission in the structure, and fully integrates coaxial transmission technology, digital frequency conversion technology and group computer combination control technology, greatly improving operating efficiency. It has performance advantages such as energy saving, environmental protection, space saving, and comfortable ride.

VVVF frequency conversion door-motor system

The constant torque characteristics and unique curve operating state can smoothly adjust the elevator speed, which greatly improves the comfort of elevator operation, leveling accuracy and operating noise.
The clever design of the door operator system will not affect the height of the car, making the entire system safe, reliable and running smoothly.

Elevator group control and deployment system

AűLPHF elevator adopts intelligent group control and deploymentsystem, greatly reduces the waiting time of passengers and runningtimes of elevator,improves the efficiency of elevator group controlsystem, with energy-saving efficacy of more than 30%.

Unexpected more of the car in leveling zone

As for uninstructed move within the lock area when the elevator stops at a landing floor and the door is open, with the detecting device installed in the elevator well sending signals to the control system,AűLPHF elevators special protection device that prevents the car from unexpected move activates wire holder to stop the car safely so as to ensure that passengers get in and out safely.

Powerful 32-bit integrated control system

Exclusive integrated elevator control system embracing 32-bit DSP motherboard for high-speed operation realizes vvvF control of elevator and diveraifies personalzed control of traction machine.car signal.load detection and floor NO.signal,for robust smooth running and passengers’comfortable experience.
