Main components of passenger elevator
Protect humanity with the standards of The Times. Great Wall high-end business passenger elevator, luxury configuration, smooth operation, from the integrated control panel to the oversized, ultra-high luxury car, inject modern design concept and environmental psychology analysis, make the whole space more vivid coordination.
Permanent magnet synchronous gearless traction machine
The gearless elevator is directly driven by a high efficiency, low speed, large torque permanent magnet synchronous gearless traction machine. Compared with the traditional elevator traction machine, the permanent magnet synchronous gearless traction machine has many unique advantages:
The gearless traction machine has the characteristics of simple structure, small volume and light weight, creating more floor space for users, greatly reducing the height of the machine room, and effectively reducing the building cost.
The gearless traction machine adopts rare earth permanent magnet material, which does not need additional stator excitation current, and can greatly improve the motor power factor; The compact gearless driving mode replaces the reduction gearbox and coupling in the traditional gear traction machine driving mode, thus greatly improving the transmission efficiency and increasing the operating efficiency by more than 50% compared with the traditional gear system. The heat energy consumption of the motor itself is very low. Combined with advanced frequency conversion control technology, the whole system has significant energy saving effect.
Green and environmental protection
The gearless traction machine does not need a complex lubrication system, which completely solves the environmental pollution problem caused by oil leakage of the traditional traction machine, and meets the maintenance free environmental requirements of the elevator. At the same time, the electromagnetic filter eliminates the mutual interference with other electrical systems in the building, avoids electromagnetic pollution, and brings green space to the surrounding environment of users.
Quiet and durable
On the one hand, the gearless traction machine has no wear, vibration and noise of the mechanical reduction mechanism; On the other hand, the gearless traction machine adopts the direct drive mode, the motor runs stably at low speed, and there is no stepping phenomenon when running at the speed of 0.2r/min, and the elevator noise is ≤ 51dB; The phenomenon of vibration and noise is eliminated, and the rare earth permanent magnet ensures the high efficiency, durability and durability of the traction machine.
Safe and secure
The professionally designed brake directly acts on the motor traction wheel, which can ensure the reliable braking and stopping of the elevator under all circumstances. It does not need to be equipped with a special uplink overspeed protection device, which fundamentally ensures safety and reassures users.
