SEW-EURODRIVE R37DRE100LC4BE5HR/ASB4/TH is a 3-phase AC inline helical gear motor. It reduces an input speed of 1750 RPM down to a 346 RPM output while delivering a rugged 5 HP rating under a standard 460V power supply.

Technical Nomenclature BreakdownSEW-EURODRIVE model numbers are highly specific codes that outline every mechanical and electrical option built into the unit:

• R37: Identifies the gearbox series and size. The R designates a foot-mounted, inline helical gear unit, while 37 represents the specific case frame size.
• DRE100LC4: Represents the high-efficiency AC motor type. DRE is SEW's designation for their energy-efficient motor series, 100LC specifies the motor frame size/stator length, and 4 indicates a 4-pole configuration (giving it the baseline ~1750 RPM synchronous speed).
• BE5HR: Denotes the integrated mechanical safety brake option. BE5 means it has an attached 5 Nm capacity electromagnetic disk brake, while HR stands for a manual brake release mechanism (hand lever).
• ASB4: Identifies the specific plug-in connector system style utilized for rapid field wiring or modular component swaps.
• TH: Indicates a built-in Thermostat (positive temperature coefficient/PTC thermistor) protecting the motor windings against thermal overload or excessive heat.
• Performance & Core SpecificationsInput Speed: 1750 RPM
• Output Speed: 346 RPM
• Power Output: 5 HP (Horsepower)
• Voltage System: 460 V AC
• Enclosure Style: TEFC (Totally Enclosed Fan Cooled)
• Phase Requirement: 3-Phase
