Non machine room lift
|
| Summary
Adopting world newly driving technique, GPN20 machine roomless and GP28 mini machine room gearless elevators are real environmental protection green elevators, which bring the power saving conception from Europe to China and lead the elvator developing trends.
The advantageous performances
Save more power: High efficiency synchronous motor,the power consumption of this kind of motor is 60% of the traditional traction machine. It can save a considerable powercost in each year.
Lower noise: Super low-speed synchronous motor reduces vibration and eliminates the noise completely from the high speed running gear and high running motor.
More reliability: The gearless traction machine, which is driven by synchronous motor directly, is just a low-speed motive part that ensures the elevator running reliably long time.
More compact: The weight of this AC gearless traction machine is the half of traditional traction machine, so it reduces the machine room space.
Security: Self-generating type energy loss brake effectively prevents from sliding danger.
More comfortable: VVVF drive system ensures that there is no peak currency, which means the elevator runs smoothly and has a more comfortable riding.
More flexible: Having the advantage of light weight and small size, this AC gearless traction machine creates the possibility to design machine roomless and small machine room elevator, which not only saves the cost of building but also provides more freedom space for architect. |
