Product Description:

The SS451-1016 is a high-performance Slo‑Syn synchronous motor designed by Danaher for latest industrial applications requiring precise low-speed control. It works on 120 VAC and supports 240 VAC in related models, making it adaptable to standard power supplies without the need for specialized transformers. Delivering a minimum torque of 450 oz‑in (318 Ncm), it reliably handles heavy loads with zero slippage. Operating at 72 RPM on 60 Hz and 60 RPM on 50 Hz, this commercial motor ensures smooth, vibration-free motion across global power systems. Drawing approximately 5.5 Amps, it balances high output with controlled energy use, minimizing heat buildup during long cycles.

Designed for durability and ease of integration, the unit uses a NEMA 34 frame and 90 mm housing, which support robust mechanical loads while simplifying retrofits into existing systems. The AC synchronous motor utilizes a 14 µF capacitor for accurate phase shift, enabling smooth startups and stable torque across varying loads. Its ability to reach full synchronous speed within 5–25 milliseconds enhances performance in high-cycle environments by minimizing operational delays. Available in leaded, terminal box, and connector wiring options, the component adapts easily to different installation setups and streamlines electrical connections in the field.

Engineered for reliability, this single-phase motor supports continuous-duty operation under classification S1, maintaining thermal balance during nonstop cycles. Its high-torque design is particularly suited for low-speed industrial settings, where force consistency and load stability are essential. The SS451-1016 variant is available in UL Listed and CE-certified versions, making it suitable for international use and reducing compliance hurdles during system integration. Backed by the best quality standards, the model offers long-term performance assurance, helping safeguard critical processes and minimize maintenance overhead in demanding industrial environments.
