The skeleton movement of an early British synchronous clock of the non self-starting type.
[edit] How it works
The rotor is of soft iron and has 36 poles: it runs in self-aligning bearings provided with a small reservoir for lubricant. It is fitted with a flywheel, so that a very brief interruption of electric supply will not cause a stoppage. The clock is provided with a simple hand starting device.
