3L passenger elevators have adopted an advanced gearless traction machine, with an energy-saving of 30%.And at the same time it has reduced the size of the elevator machine room,providing more free design space for architect.The Elevator is controlled by the latest 32 bytes microomputer system,which provides more accurate and efficient running control.
3L not only uses VVVF tech in the main motor,but also in the door motor,
plus the unique door control structure whick enables the door to open and close steadily and quietly.Custoners also have many choices for decoration of advantageous Performances of Small Machine Room Elevator
Low noise
Low-speed synchronous motor reduces vibrations and eliminates noise completely.
More reliable
The use of high quality materials and low cost running ensure the elevators run more reliably and for a longer service time.
Comfort
The VVVF vector-driven elevator has no peak value current and makes the elevator more steady and confortable.
Saving energy
The highly efficient synchronous motor,the power consumption of this kind of motor is only 70%compared with the traditional traction machine.It can save considerable cost for power eachyear.
Maintenance
The maintenance-free gearless traction machine doesn’t need to be filled up with lbricating oil ,and this can protect the environment.
