With the development of the world's economic skills, elevator skills are also developing rapidly, we are more and more uninterested in the elevator machine room, the current machine-roomless elevator uses a lot of cutting-edge skills in the industry. The following editorial to introduce the machine-roomless elevator skills characteristics:

1. The gearless traction machine of the elevator is extremely compact because of the selection of a number of leading miniaturization skills, such as permanent magnet motor, common stator structure and embedded double brake layout.

2. Optimized motor planning also greatly reduces the torque pulsation that directly affects the comfort of elevator operation, and the compact mechanical structure operates more smoothly, quietly and comfortably than previous products.

3. In terms of elevator drive, the use of leading technologies such as high-storage large-scale integrated circuits and low-noise PWM inverter components makes the variable voltage and frequency control of the drive equipment for the traction machine more accurate and smooth, and the IPU (integrated power unit) and PM (permanent magnet) motor as the power supply system for the motor drive circuit greatly reduces the energy consumption.

4. The new direct-drive door system uses the same permanent magnet motor and places it inside the door mechanism, which not only saves space, but also makes the door opening and closing action more stable and quiet.

5. The control of door circuit utilizes high-performance chip to strengthen the sensitivity, which can be accurately controlled according to the different conditions between floors. The control box is installed in the side wall of the car, after entering the car, you don't need to turn around to register the command signal. 6.

6. Inside the car, the planning is very humanized, the display adopts large font, the height of the command buttons is reduced compared with the past, so that anyone can operate conveniently. Set these high-tech effects in a machine-roomless elevator for the user means more safe and reliable, more comfortable to enjoy the elevator, and on the elevator maintenance unit, it is required to higher skill content, more accurate and standard operation.
