SS451T by Danaher

The Danaher SS451T synchronous motor is a precision stepping motor from the Slo-Syn Synchronous Motors series designed for industrial automation applications. It delivers a Rated Torque of 450 oz-in at a steady Speed of 72 RPM (60 Hz) and operates on a Voltage Rating of 120 V AC single-phase. The primary function of the SS451T is to convert single-phase input power into consistent, step-based rotational output, making it ideal for machinery that demands accurate positioning and repeatable motion control.

Featuring a robust Motor Type of Synchronous, Type A design and an Operation Mode of single-phase with phase-shifting network, the SS451T manages a Current Draw of 0.8 A. It requires a Capacitor Requirement for single-phase operation to ensure proper phase shifting and reliable performance. The motor is rated for use at 60 Hz and mounts via a Terminal box mounting installation. Its compact footprint and Connector Dimension of 5.65 in (144 mm) facilitate straightforward mounting and conduit or cable gland integration.

In addition to its core specifications, the SS451T offers broad compatibility with NEMA frame sizes (34D) and accommodates a maximum linear force of 50 lb and radial force of 25 lb. The motor’s Electrical Connection through a dedicated terminal box enhances serviceability, while its Net Weight of 14.3 lb (6.5 kg) balances stability and ease of handling. The unit supports torque requirements with a minimum holding torque of 550 oz-in on a single winding and 700 oz-in with both windings energized. By fulfilling industrial standards for precise torque delivery and controlled inertia, the Danaher SS451T reduces system complexity, improves repeatability, and elevates overall operational efficiency in demanding automation environments.
