This should be easy enough for the mechanically inclined Sdopers. What is synchronous speed for a motor? If it matters, this question is regarding motors used on industrial pumps, so I WAG they must be three-phase AC motors. Is it 3600 rpm?
Does it have something to do with 60 Hz * 60 s/min = 3600?
That’s exactly why. A synchronous AC motor has an armature surrounded by non-moving windings. The AC current through the windings creates a rotating magnetic field that spins the armature. With a 60HZ line frequency, the magnetic field, and hence the armature, rotates 60 times per second. 60 HZ times 60 seconds per minute = 3600RPM.
