NEMA B42/B48 Frame Motors

Compact NEMA Frame Motors for OEM & Equipment Applications

NEMA B42/B48 Frame Motors are compact-footprint single-phase and three-phase induction motors built to NEMA dimensional standards, popular for North American export equipment and OEM applications globally. These small-frame motors deliver 1/4 HP to 1.5 HP at standard NEMA voltages (115/230V single-phase, 200/230/460V three-phase) with frame dimensions per NEMA MG 1 specifications.

Bombay Engineering Syndicate supplies Crompton-make NEMA B42 and B48 frame motors used by export-oriented OEMs, equipment manufacturers, and aftermarket replacement segments. Typical applications include small pumps, fans, blowers, conveyors, agitators, and packaging machinery — anywhere a compact NEMA-dimensioned motor is required for domestic or international equipment builds.

Construction features include rolled-steel or aluminium frames, sealed ball bearings, Class B/F insulation, IP44/IP54 protection, and NEMA-standard shaft extensions (5/8" and 1/2" keyed). Mounting variants include resilient-base, rigid-base, C-flange, and ODP (open drip-proof) for indoor applications.
