Bonfiglioli C, A, F, S & VF/W Gearmotors

Overview

Bonfiglioli's industrial gearmotor range covers the everyday drives in a plant: helical inline (C and EVOX CP), helical-bevel right angle (A), parallel shaft (F), single-stage helical (S) and worm (VF/W). Most are available as complete gearmotors or as reducers with an IEC or NEMA motor input, and the C, A and VF/W Series are offered in ATEX versions for hazardous areas.

Gordon Russell supplies the full range and can package the gearbox with the motor, coupling, brake and drive. For very high reduction ratios, A and VF/W units combine with the Bonfiglioli 300 Series planetary units we build in our own shop.

Series

Ratios 2.6 to 1,481
IEC or NEMA motor input, or BMD servomotor
ATEX versions

Bonfiglioli C Series helical inline gearmotor

EVOX CP · Compact Coaxial

Compact coaxial gearmotors built on a market-standard footprint, so they drop in where an existing inline unit sits.

55 to 650 Nm
Ratios 2.3 to 187
IEC or NEMA input

Bonfiglioli EVOX CP compact coaxial gearmotor

A Series · Helical-Bevel Right Angle

Right-angle helical-bevel gearmotors that turn the drive through 90 degrees at far higher efficiency than worm gearing. A good fit for continuous-duty conveyors.

Ratios 4.9 to 1,715
0.22 to 150 kW
BMD servomotor version; ATEX versions
Combines with the 300 Series for higher reduction

Bonfiglioli A Series helical-bevel gearmotor

F Series · Parallel Shaft

Parallel-shaft gearmotors for drives where the motor sits alongside the driven shaft.

140 to 14,000 Nm
Ratios 6.4 to 2,099
IEC or NEMA input

Bonfiglioli F Series parallel-shaft gearmotor

S Series · Single-Stage Helical

Single-stage helical units for pumps, fans and blowers.

Single-stage helical gearing
See the C / A / F / S catalogue for ratings

Bonfiglioli S Series single-stage helical gear unit

VF / W Series · Worm

Compact, quiet right-angle worm gearmotors for lighter, intermittent or space-limited drives.

VF/W: 13 to 7,100 Nm; W Series: 200 to 830 Nm
Ratios 7 to 100
NEMA versions; ATEX versions
Combines with the 300 Series

Frequently Asked Questions

Can I get these gearmotors with a NEMA motor?

Yes. The C, A, F and VF/W Series are available with NEMA motor inputs, and EVOX CP takes IEC or NEMA input. Tell us the motor frame you run today and we will match the input.

Inline, helical-bevel or worm: which should I choose?

Helical inline (C, EVOX CP) is the most efficient choice when the motor can sit in line with the driven shaft. Helical-bevel (A) turns the drive 90 degrees with similar efficiency, which suits continuous-duty conveyors. Worm (VF/W) is compact, quiet and cost-effective for lighter or intermittent duty. We can help you compare running costs.

Do you supply the motor as well?

Yes. We supply complete gearmotors, and we also represent TECO-Westinghouse, WorldWide Electric and Bonfiglioli motors and variable frequency drives.

Are ATEX versions available for hazardous areas?

Yes. The C, A and VF/W Series are offered in ATEX versions. Let us know the zone classification and we will confirm the right configuration.

Can these units replace another manufacturer's gearmotor?

Often, yes. EVOX CP is built on a market-standard footprint for easy replacement, and we can compare dimensions and ratings for other series. Send us the nameplate and a photo of the existing unit.
