Marcon 7M04 Oriental Motor AC Synchronous Motor 250VAC Made in Japan

Marcon 7M04 Oriental Motor AC Synchronous Motor 250VAC Made in Japan

The Marcon 7M04 is a small AC synchronous motor manufactured by Oriental Motor under their Marcon brand, rated at 250VAC. It features a compact cylindrical aluminum body with a black plastic dome cap, a flat metal mounting bracket, and two bare-ended lead wires for straightforward integration. The unit's cylindrical form and lightweight construction make it well-suited for instrumentation and light-duty timing applications where consistent synchronous speed is required.

Applications

AC synchronous motors like the Marcon 7M04 are used in applications where a constant, speed-stable rotational output is needed in direct relationship to the AC line frequency. They are commonly found in timing mechanisms, chart recorders, scientific instruments, analog clocks and timers, industrial control equipment, and other devices where synchronous speed consistency matters more than high torque. Oriental Motor is a well-established Japanese manufacturer with a long history of producing precision small motors for instrumentation and light industrial use. The Marcon designation was used on their capacitor and motor products for the Japanese domestic and export markets. Units like this date from an era — broadly the 1970s through 1990s — when small synchronous motors of this cylindrical form factor were widely specified in both laboratory instruments and OEM industrial equipment. They remain in demand as replacement parts for legacy equipment still in service.
