Machine Room - Less

	"INS " Machine Room - Less
	The tracton machine is mounted on the machine beam of top floor, compatared with the conventional elevator, it has no machine room with cost saving. At the same time it makes the building appearance much more compact and improves the rate of utilization for building space accordingly. adopting the gear less synchronous external rotir traction machine, to achieve energy saving, as there is no slowing down device so there is no need for gear lubricant, wich will save the cost of its replacement, No power loss so slowing down device in the machine-room-less elevator and the use of high efficient permanent magnet motor save more than 40% energy consumption and the electricity expenditure for the user, compared with the conventional elevators. There is only one motion component in this machine which s of gearless structure with slow speed rotation, thus ensure long stable running and superior leveling accuracy.
