Machine room car(MRC) elevator is provided with a new generation of permanent magnet synchronous gearless traction machine, through a perfect combination of VVVF variable frequency control technology, achieving a safe and stable access of cars, meanwhile saving the 80% construction area occupied by traditional car ramp, reducing 30% or more energy consumption of elevator.
Using a machine roomless structure configuration, the floor space is small, the civil requirements are low, and the project costs are low, so that it can be easily integrated into the building structure.
