spins down

Loses rotational momentum

Spins down describes the gradual slowing of something rotating until it stops—a hard drive, a centrifuge, a turbine.

In computing, a drive spins down to save power when not in use: The server spins down idle disks after fifteen minutes.

The phrase implies controlled deceleration rather than abrupt stopping.
