How much power does an elevator use? The power supply of the elevator traction machine is measured by a clamp meter. At 380 Volts, it is dynamically adjusting current for startup (13 amps), cruise (6 amps), changing rope length (weight) and stopping,

Elevator speed: 90 m/min, carrying 600 kgs (full load) of iron weights.

http://www.pbs.org/wgbh/nova/ - Tom Magliozzi has a problem. The wacky co-host of NPR's Car Talk needs to replace his beloved 1952 MG roadster. But where do you turn to in today's car market? Is new technology about to transform the way we drive?

Traction motor and computer unit for a modern Mitsubishi H-GPS4 series elevator, Running at inspection speeds but is rated for 60M/min. (technician is driving car down via remote-control).

Nowadays most of the elevator components (traction motor, door driver) are running on three phase, 10KHz power at variable voltages; this is controlled by digital computer. It's called VVVF, for variable voltage and frequency. This is NOT a DC motor as I previously understood.

Input power is 220VAC single-phase, transformed up to 400 VAC before entering the system (which changes power output as needed).

Other than the sound of the ventilation fan (the computer circuit cabinet) and the occasional sound of the brakes, the only sound from the traction motor is a high frequency (10KHz) hum. There are inspection controls in the cabinet, as well as three LED digit displays displaying current floor and operation status (stop, up/down, etc). Apart from several "Mitsubishi" chips, an Intel 80386 CPU is at the core of its processing power. The motherboard equipment is not unlike a PC case or server, but there are voltage coils underneath. The motherboard will be covered by a vented panel when the car is due for service.

此短片展現的是三菱電梯智慧節能型的電梯驅動馬達，第一次運轉， 平衡垂才剛剛裝上，以低速(維修人員遙控操作)向下行駛中。

幾乎所有的電梯設備都改採調頻變壓供電，包括車門驅動馬達以及捲 場馬達。交流電源頻率10千赫以上，電壓由控制設備微調輸出 0V~380V 電力。機房控制箱內包括行車控制。調頻變壓系統簡稱 VVVF, 並非是直流電.

機房電力輸入採用原有單相 220V, 經過變壓器轉成 380VDC 輸入到控制設備，由電腦調整所需要的輸出。

影片中最大的噪音來自控制設備本身的散熱風扇，除了碟盤煞車偶爾 作動的聲音外，並無其他可辨別的噪音。捲場機的馬達採用高頻運轉 ，接近無聲。

機殼內有工程人員用來直接控制電梯的開關，也可透過板子上的LE D數字直接判讀車廂位置，運轉狀態。電路板的核心運算 採用 Intel 80386 晶片運作。平常是蓋起來的，跟一般PC沒有兩樣，除了下方有許多 高壓變電線圈..
