Industrial TC-FX FB-1B Three-Phase Induction Motor

Sumitomo SM-CYCLO TC-FX/FB-1B is an industrial three-phase induction motor from the SM-CYCLO family, offered as the TC-FX/FB-1B brake-motor variant. It accepts a 230–460 V, 60 Hz power supply and delivers a nominal 0.75–1 HP with a speed of about 1,720 RPM, packaged in the compact V-80S frame. This four-pole design is intended for general drive duties in equipment where braking control is important, with the FB-series design developed to integrate braking capability into Cyclo‑driven drive trains. The model is noted as discontinued by the manufacturer in 2017, though used and refurbished units continue to appear on secondary markets. Buyers should verify current availability and account for any brake‑control wiring or mounting accessories associated with FB-series brakemotors, as well as confirm compatibility with existing mounting footprints provided by the V-80S frame. In practice, TC-FX/FB-1B’s 230–460 V, 60 Hz rating and its brake-motor designation position it as a drop-in consideration for retrofits or new builds that require reliable start-stop performance within a compact, standard industrial footprint.
