Study Notes
Otis GeN2 Comfort System
- The GeN2 system is a highly efficient machine that is up to 50% more efficient than conventional geared machines and 10% more efficient than conventional gearless machines with induction asynchronous motors.
Key Features
- The system uses a flat belt and a smooth crowned sheave, which provides a more compact machine.
- The gearless machine has sealed-for-life bearings, which eliminates the need for polluting lubricants.
- The system is equipped with a highly efficient PM synchronous motor of radial construction, which is 15% more efficient than other machines with PM motors of axial construction design.
Environmental Benefits
- The lubrication-free and energy-efficient system reduces operating costs and increases system reliability.
- The system consumes less energy, with substantial energy cost savings when compared with conventional machines.
- The reduction of power installed reduces operational cost, and the lower starting and nominal currents reduce the feeder size lines and installation costs.
Reliability and Safety
- The long-lasting coated steel belt, smooth crowned sheaves, and reduction of moving parts in the gearless machine increase durability and reliability.
- The Otis PULSE electronic system monitors the status of the belt's steel cords 24/7, detecting and informing technicians on the quality of the belt cords, eliminating downtime and enhancing reliability.
- The system includes safety features such as a door deterrent device, which prevents the car door from opening if the car is stopped between floors.
