Detailed Product Description

QUINTESSENCE ON ENERGY SAVING BUILDINGS

GreenMax-E Passenger Elevator with Mini machineroom is an extended product of GreenMax permanent-magnet synchronous gearless elevator with mini-machine room developed by Guangzhou Guangri Elevator Industry Co., Ltd. It inherits the excellent characteristics of GreenMax elevator, which can minimize the energy consumption by means of the latest energy saving technology with stable quality and reliable properties and safe operation and will be the best choice for energy saving buildings.

Energy Saving Technology
By means of the most advanced control and driving technology in the world, the operating efficiency of GreenMax-E elevator can be improved, the energy consumption can be reduced and the maintenance cost can be lowered.
→Driven by the advanced permanent-magnet synchronous gearless traction machine in the world, the efficiency of the system of GreenMax-E elevator will be 30% higher than that of the elevator driven by traditional traction machine.
→32-bit microprocessor integration control system and high-bit multi-CPU coupled with precise space vector position controller enable the completely closed loop vector control between the controller and the traction machine, thus quicken the response speed and enhance the reliability of the system and improve the operating efficiency of the elevator.
→When driving the elevator doors of different weight, the permanent-magnet synchronous variable frequency door operator, 32-bit industrial-class microprocessor three-closed-loop (speed loop, current loop and moment loop) servo control with high precision and the advanced vector control calculation method enable the automatic adjustment of moment and self-adaptability of door weight, which can not only save the energy, but also make an efficient and smooth door opening/closing speed curve and lower the noise.

Safe and Reliable
→Direct brake traction wheel and braking force over-redundancy design can assure the reliable stop or quiescence of the elevator.
→Complete safety protection measures enable the real time protection for elevator in case of failure and record the faults precisely and analyze the relative causes.
→The most advanced direct parking technology and sensorless automatic load compensation technology in the industry make the elevator run more smoothly, level more precisely and ride more comfortably.
→CAN bus communication technology can assure the high reliability and precision of information transfer and avoid mal-function effectively.

Environment Friendly
→The occupation area of small size machine room is equal to the vertical projection area of the shaft, which is only 40% of the traditional machine room. The height of machine room can be reduced and the construction cost can be saved.
→No liquid lubrication oil is necessary for gearless traction machine. The oil pollution can be reduced, thus the environment can be kept clean. The noise and vibration caused by traditional driving can be eliminated.
→The advanced VVF integrated control system instead of traditional driving and control connection can eliminate the electromagnetic radiation caused by strong current between the connection lines, reduce the electromagnetic pollution and keep the passengers healthy which show humanistic care for passengers.
