Machine Roomless Elevator
The machine-room-less elevator is the result of technological advancements that often allow a significant reduction in the size of the electric motors used with traction equipment.
Permanent magnet synchronous gearless traction technology
The gearless traction machine with the new PM (permanent magnet) motor is packed with cutting-edge technology, such as our unique stator-core structure and built-in double brakes. This optimized motor design dramatically reduces the level of torque ripple for a smooth and quiet movement. The 32bit microcomputer and VVVF control technology, acts as a high efficiency power supply circuit for the motor drive and, along with the PM motor, delivers greater energy savings.
The adoption of the low-noise with faster switching speeds also contributes to further reduce the noise. The result is a more efficient, more reliable drive control. The VVVF Inverter Control has been adopted to ensure smoother and quieter door operations, thereby enhancing passenger safety and product reliability. It adjusts the door open and close speeds, as well as the door motor torque as needed for each floor using the Auto Tuning function. The learning capability loads detector immediately reversing the doors when abnormal load is detected on the doors.
OUR KEY COMPONENTS
The miniaturization of the traction machine, leading to the development of the gearless traction machine with PM motor enables a hoistway to include in the upper section the driving devices that were installed in a machine room.
Besides that, the square area of the hoistway is almost the same as our conventional elevator, contributing to space saving in your building. All you have to think about in your planning now is a hoistway only.
