SS242LEG4

The Danaher SS242LEG4 synchronous motor from the Slo-Syn Synchronous Motors series delivers precision AC-driven performance tailored for demanding industrial automation applications. This AC synchronous, NEMA 34 frame motor features an integrated 4:1 gearbox to multiply output torque while reducing shaft speed, yielding smooth, repeatable motion. It operates on a standard 120/240 VAC power supply, enabling compatibility with both 60 Hz and 50 Hz systems. The compact Frame Size (a max) of 2.72 in (69.9 mm) and leaded plug configuration facilitate swift installation and straightforward wiring in tight spaces. Rugged design elements ensure consistent speed control and low vibration across diverse operating conditions.

Detailed technical specifications underscore the SS242LEG4’s suitability for harsh industrial environments. The enclosure is rated IP42 to resist dust ingress and light moisture, while the operating temperature range spans –40°F to 140°F (–40°C to 60°C). Storage temperature tolerances extend from –40°F to 266°F (–40°C to 130°C) for versatile deployment in variable climates. The motor sustains reliable operation in 5–95% non-condensing humidity and at elevations up to 30,000 ft (9,100 m). Connection is simplified through a Leaded plug configuration, and the inclusion of an Extended rear shaft option allows easy addition of encoders or couplings for specialized feedback or power transfer configurations.

Operational performance highlights the motor’s ability to deliver a Minimum Running Torque of 240 oz-in even under heavy startup loads, preventing slip in jam-prone systems. It achieves full synchronous speed in just 5–25 ms, enabling rapid acceleration and precise cycle timing in high-repetition processes. The unit operates at 72 RPM (60 Hz) and 60 RPM (50 Hz), maintaining speed consistency across global power standards. Designed to stall indefinitely without damage, it offers secure holding capability without overheating. These features combine to enhance throughput and reduce downtime in continuous and intermittent duty cycles.

Integration into automated machinery is streamlined by the motor’s compatibility with standard NEMA 34 mounting patterns and the leaded plug interface. The robust gearbox and extended shaft provision support direct coupling to conveyors, indexing tables, and rotary actuators without external reducers. Ideal applications include packaging machinery, pick-and-place systems, labeling equipment, and precision indexing in assembly lines. The SS242LEG4’s compact footprint and rugged specifications make it a versatile choice for system integrators seeking reliable, low-maintenance synchronous motion solutions.
