These are driven by AC electric motors.
Geared Machines are coupled machines with AC electric motor, electromagnetic brake, worm reduction gear & friction sheave mounted on bed plate. These components are rested on machine room bottom slab by using rubber pads for noiseless and vibrations less operations.
Normally installed in the machine room above the lift well.
Considered as future technology in elevator industry also known as Permanent Magnet
Synchronous Motors (PMSM).
Compact size, lighter in weight, simplified construction hence easy to install and
maintain.
PMSM uses a rare earth material with high magnetic flux density.
Higher mechanical torque, output power per volume. Better dynamic performance than
electromagnetic excited motors.
Gearless machines saves app. 40-60% energy than traditional traction machines, Improved
Life Span, thereby, proving more economical to the end users in long term.
Collective Memory System is best suitable for low rise residential buildings where main requirement is to go from ground floor to any specific floor and vice versa. This control system registers and retains in memory, the down hall calls and car calls. These are answered in a logical order to ensure minimum necessary car movement, resulting in quick response to passenger traffic and thereby substantial power saving. If the elevator is moving in upward direction, it will respond to car calls in floor sequence and the highest down hall call only. Once the car reaches the highest registered call it will reserve and collect all hall calls in floor sequence during downward movement.
Full Collective Memory System registers and retains in memory, the calls of both directions
and
hence is best suitable for high rise residential buildings and commercial / industrial
buildings where
in addition to the movement between ground floor and specific floor there is also a need to
serve
inter-floor traffic.
On every landing there will be two buttons for Hall Calls, one for upward direction and
other for
downward direction (except for starting and top landings). While elevator is moving in
upwards
direction, the lift will attend all Car calls and only Up Hall calls and while moving in
downward
direction it will attend all Car calls and only Down Hall calls in logical sequence and thus
results in
substantial power saving.
This system is applicable where two lifts are next to each other. Duplex System is available in full Collective Control System and uses logic to dispatch nearest lift in the direction of travel to collect the waiting Passenger thereby reducing power consumption and waiting time. This Control system along with VVVF Drives reduces power consumption by upto 40% and also saves time.
In case of power failure this will help to bring the Lift at nearest Floor. This system works on batteries and comes into play only in case of power failure. This helps to bring the lift to the nearest floor thus allowing anyone trapped inside to come out easily. Now ARD is mandatory for every new lift as per circular issued by Inspector of Lift Mumbai.
This system is entirely based on Automatic Operation which gets triggered within approximate
time of after power failure detection.
Inbuilt Direction selection feature resulting into quick rescue operation by going to the
nearest
floor and stands with doors open.
Compact Device with batteries placed safely inside the system.
All the operations are Automatic avoiding any Human intervention in rescue operation.
As car air conditioner has become a standard feature in any modern car, V3F drive is an
essential
feature of modern elevator and it is real value for money. Here are some of the salient
features of
elevator with V3F Drive
Smooth Start & Stop
Better Level accuracy irrespective of Load
Extra Loading Capacity
Reduces Breakdowns
Improves Life of Lift
Reduces Electricity consumption
Floor Announcement System
Soft Music while lift is working
Better integration with generator or battery backup Inverters

This device indicates the overloaded condition and prevents lift from operating till load is adjusted. Now even this is mandatory for every new lift as per circular issued by Inspector of Lift, Mumbai.
Low voltage & Noiseless operations with V3F Door Motor.
Programmable opening / closing speed & time.
