What is the normal RPM for a car when starting?

[Tyler]

When just started, generally 1000 RPM is considered normal, as the engine typically doesn't rotate too fast during startup. Introduction to RPM: Rotational speed (Rotational-Speed or Rev) refers to the number of revolutions an object moving in a circular path completes around the center of the circle per unit time (different from frequency). Common rotational speeds include rated speed and maximum speed. Structure of RPM: Hard disk rotational speed is expressed in revolutions per minute, with the unit denoted as RPM, which stands for Revolutions Per minute. The higher the RPM value, the faster the internal transfer rate, the shorter the access time, and the better the overall performance of the hard disk. Function of RPM: The spindle motor of the hard disk drives the platter to rotate at high speed, generating buoyancy to make the magnetic head float above the platter. To bring the sector containing the data to be accessed under the magnetic head, the faster the rotational speed, the shorter the waiting time. Therefore, the rotational speed largely determines the speed of the hard disk.
