SS241ETG4

The Danaher SS241ETG4 from the Slo-Syn Synchronous Motors series delivers a robust single-phase synchronous motor solution engineered for precision low-speed applications. This industrial automation component operates on 120/240 VAC ±5% at both 50/60 Hz, ensuring compatibility with global power standards. The integrated 4:1 gear reduction gearbox produces a reliable output speed of ~18 RPM while maintaining a rated torque of 240 oz-in (169 Ncm) with zero slip. Designed for heavy-duty performance, the SS241ETG4 excels in delivering consistent motion control in conveyor, packaging, labeling, and printing systems. Its compact footprint and economical design reduce space requirements and system cost without sacrificing durability or control accuracy.

The technical architecture centers on a single-phase winding configuration that draws ~2.5 A under normal load, minimizing thermal stress and power consumption. Operating at 72 RPM (60 Hz) or 60 RPM (50 Hz) synchronous speed, the motor reaches full speed within 5–25 milliseconds, enabling rapid response to start/stop commands. The enclosure features an IP42 rating, protecting internal components from solid intrusion and light moisture. Environmental resilience is further enhanced by an operating temperature range of –40 °F to 140 °F (–40 °C to 60 °C) and storage capability from –40 °F to 266 °F (–40 °C to 130 °C). Humidity tolerance spans 5–95% non-condensing, ensuring reliable insulation performance in varied ambient conditions.

Mechanical performance parameters include a radial shaft load capacity up to 18 lbs and an axial load limit of 3.5 lbs, extending bearing life and reducing maintenance intervals. The motor’s synchronous design eliminates slip, delivering precise positional accuracy for repeatable motion tasks. A 7.5 μF/250 VAC capacitor is integrated to provide proper phase shifting, stabilizing torque under varying loads. Compliance with UL 508 standards certifies the SS241ETG4 for safe operation in U.S. and Canadian industrial environments. The motor’s rugged construction supports millions of duty cycles, making it suitable for continuous operation in automated production lines.

System integration is streamlined through standardized mounting dimensions and dual voltage terminals that facilitate rapid field installation. The open-loop synchronous characteristic removes the need for complex feedback devices, simplifying control schemes and reducing overall system complexity. Ideal target applications include conveyor drives requiring controlled low-speed motion, packaging machines demanding precise fill-and-seal cycles, labeling units needing consistent speed, and printing systems where repeatability and torque stability are critical. The SS241ETG4’s combination of durability, efficiency, and integration ease positions it as a versatile component for diverse industrial automation tasks.
