The National Time 2M Series clock mechanisms are economical yet employ the exclusive worm-gear drive technology similar to its bigger cousins. The 2M mechanism is driven by a permanent magnet, 115V 50Hz or 60Hz synchronous gear motor. These mechanisms offer mounting options to suit all applications with dial sizes up to 42″ diameter. Custom shaft lengths up to 10” can be provided to meet specific project requirements.
The 2M version is a stand-alone clock that keeps time using the 60Hz power line. The synchronous motor provides smooth continuous movement of the hands. Time correction is accomplished by manually spinning the minute hand until the correct time is reached.
The 2MR Synchronous version employs an additional 10 rpm motor providing means to electrically adjust the clock at 10 times speed. The 2MR can be controlled by any of our Master Clock Controllers and will be automatically corrected following power loss and daylight saving adjustments. 2MR clock mechanisms are also with 970 Series manual switch panels.
