Product Description:

The KSL091T1Y synchronous stepping motor is manufactured by Danaher within the Slo-Syn Synchronous Motors series. It converts line frequency directly into controlled incremental motion, letting automation equipment index fixtures, valves, or small conveyors without feedback electronics. By operating at a constant electrical step rate, the motor supplies repeatable displacement and maintains position when stalled, making it useful where open-loop accuracy and holding torque are more important than high dynamic speed.

The electrical input is 120 VAC ±5%, and the winding draws 0.50 A from a single-phase source at 60 Hz for full-step operation. Under these conditions, the rotor supplies a minimum holding torque of 240 oz-in, even after extended dwell periods. The permitted load inertia is 4.0 lb-in², a level found in light actuators, so moderate flywheel masses can be started and stopped without losing synchronization. The R/C wiring diagram guides lead identification during panel installation. The shaft has a diameter of 0.3750 in and a 0.328 in flat, allowing set-screw or clamp couplings to seat without slipping during bidirectional operation.

The phase-shift network that drives the stator uses a 5 µF capacitor in series with a 300 Ω resistor rated for 50 W of power dissipation. That power margin keeps the surface temperature within safe limits during repeated starts. When energized through this network, the rotor turns at exactly 1.2 rps, providing a synchronous speed of 72 rpm for applications such as low-speed indexing tables on shop-floor conveyors. The frame carries an IP42 enclosure rating, offering basic protection against solid objects larger than 1 mm and dripping water. Routine cleaning with a damp cloth does not impair operation in moderate-duty installations.
