AnSUIT RF37-DRNcuireann an tsraith meicníocht helical choxaile éifeachtach le héascaíocht a meinim-sciatháin (B5)suiteáil. Trí úsáid a bhaint as an Éifeachtúlacht Préimhe IE3 DRN motor, this gearmotor is optimized for modern industrial standards, offering high energy savings and a compact footprint. The "RF" prefix specifically denotes the flange-mounted version of the standard R37 series, making it ideal for direct attachment to machine walls or hollow-frame structures.

The SEW modular system allows the RF37 to be upgraded with a wide range of functional accessories:
- Integrated spring-applied brakes (e.g., BE1 or BE2) for fail-safe stopping.
- Encoders (EI7C / EK8S): For precise speed feedback and positioning, often integrated into the motor fan cover.
- Optional oil level sensors or vibration sensors (DUV) for predictive maintenance.
- frequency inverters for variable speed control.
The RF37's flange-mounted design is specifically suited for applications where the drive must be "face-mounted" rather than bolted to a floor base:
- The RF series is a staple for small-to-medium tank mixers (often seen as the RM37 variant with extended bearing hubs).
- Direct mounting to the side plates of labeling or filling machines.
- Ideal for centrifugal pump drives where alignment is maintained via the flange.
- Drives for sorting gates, corner transfers, and vertical lifts.
Q: What is the difference between R37 and RF37?
A: The R37 is foot-mounted (it has "feet" to bolt to a floor or bracket). The RF37 is flange-mounted (it has a circular flange face to bolt directly onto a machine surface). Internally, the gears and torque ratings are identical.
Q: Can I change the flange size of my RF37?
A: Yes, SEW offers the RF37 with different flange diameters (e.g., 140mm, 160mm, or 200mm). This must be specified at the time of order as it affects the gearbox housing casting.
Q: Why use the IE3 (DRN) motor instead of the older IE2 (DRE)?
A: IE3 Premium Efficiency is now the legal requirement in many regions (EU, USA, China) for motors of this power range. It reduces total cost of ownership through lower electrical consumption and runs cooler, extending the life of the motor insulation.
