SEW Eurodrive RF17 DRS71S4BE05

The SEW-EURODRIVE RF17 DRS71S4BE05 gear motor is a compact 0.37 kW drive with a reduction gear ratio of i = 17, designed for industrial applications requiring low speed and stable torque, such as conveyors, packaging machines, and internal transport systems.

Technical Data

• Motor power: 0.37 kW
• Supply voltage: 220–230 V Δ / 380–400 V Y, 50 Hz
• Number of poles: 4 (synchronous speed approx. 1500 rpm)
• Gear ratio: i = 17
• Output speed: approx. 88–90 rpm
• Rated current: 2.15 A (220 V Δ) / 1.24 A (380–400 V Y)
• Output torque: depending on configuration, typically in the range of a few to several Nm
• Duty class: S1 – continuous operation
• Energy efficiency class: IE1
• Degree of protection: IP55 (optionally higher, e.g. IP65)
• Housing material: aluminum

Key Features and Benefits

• Reduction of rotational speed (1500 rpm motor + ratio 17 gives output speed ~88–90 rpm)
• Ensures sufficient torque with moderate power (0.37 kW = low to medium drive range)
• Suitable for continuous duty (S1) operation in devices running for long periods without interruption
• Adapted for moderate environments – IP55 protection allows operation in dusty or slightly contaminated environments, but not extreme conditions (immersion, high humidity, heavy industrial dust, etc.)
• Typical uses: conveyors, worktables, packaging equipment, mixers, internal transport systems, auxiliary machinery drives
