What you’ll learn

  1. The rotating heartIdentify the rotor, central axis, wings, pivots, and bearings that make a revolving door turn.A revolving door is one connected rotor supported around a central axis, usually with three or four wings dividing the circular entrance.
  2. A moving airlockExplain how rotating pockets control air exchange and shape pedestrian flow.The moving wings limit a direct opening to outdoors, while diameter and speed determine comfort, capacity, and the size of each passage.
  3. Safety is part of the mechanismConnect sensors, emergency breakout, and accessible dimensions to real-world door safety.A useful revolving door combines controlled motion with obstacle detection, emergency release, and enough space for varied travelers.

Questions this course answers

What is the central post of a revolving door for?

The central post or shaft is the rotor's axis and keeps the radiating wings aligned as they turn.

Why can a revolving door reduce drafts compared with a propped-open hinged door?

The rotating wings and enclosure limit the direct opening, although they do not stop all air exchange.

What is an emergency breakout feature designed to do?

Breakout systems provide a wider path when the ordinary rotating route is unsuitable in an emergency.

Why do revolving-door specifications list diameter and passage width?

The size of the rotor and its openings determines how people move through the door and what they can carry.
