Product Description:
The SS451TG4 is a geared synchronous motor produced by Danaher within the Slo-Syn Synchronous Motors series. This integrated motor and gearhead assembly supplies low-speed, step-accurate rotation for indexers, conveyors, and timing devices used in industrial automation. Its line-frequency synchronization and high holding torque support applications that require repeatable movement without an electronic drive.
The stator operates from a single-phase supply of 120 VAC. With the matched 14 µF capacitor, the motor draws a steady 0.80 A, allowing appropriate selection of circuit protection and wiring. Operation is synchronized to the mains at 60 Hz, eliminating the need for electronic speed control while producing a stall torque of 450 oz-in at the motor shaft. After the internal reduction train, the gearbox output rotates at 18 rpm, which is suitable for slow and repeatable material positioning. Input lost motion is limited to 7°, while output backlash is 2° to help control cumulative indexing error. The maximum permissible inertia is 77 lb-in² for dynamic loads. The gearbox is 1.19 inches long, and the assembly has an overall length of 6.84 inches for machine layout planning. Radial shaft loading may reach 150 lb without exceeding the bearing limit.
The integral gearset provides a mechanical ratio of 4:1, reducing the motor speed while increasing the available output torque. Power is transmitted with an efficiency of 88%, helping limit thermal rise during continuous operation. At the reduced output speed, the unit delivers up to 1,584 oz-in of torque for directly driving cams, lead screws, or small turntables without intermediate belts. Static axial loading may reach 100 lb, allowing the shaft and bearings to support thrust generated by coupled equipment. The available load capacities suit overhung and thrust loads commonly encountered in packaging, metering, and light assembly machinery.
