Product Description:

The T22NSLS-LDN-SS-02 is a hybrid stepper motor manufactured by Pacific Scientific and supplied in the T High Torque Motors series. Built around a NEMA 23 frame, it accepts pulse commands from a step drive and translates them into controlled shaft motion for pick-and-place arms, small indexing tables, and light conveyors. High torque density allows the motor to maintain position under load while occupying minimal space, a common requirement in distributed industrial automation zones such as packaging feeders or semiconductor handlers.

The motor delivers a continuous stall torque of 1.98 N·m, allowing it to hold static loads without loss of synchronism when the windings are energized. Each full step advances by 1.8°, yielding 200 discrete positions per revolution and simplifying open-loop positioning algorithms. Dynamic response benefits from the low rotor inertia of 0.0000408 kg·m², which lets the drive issue rapid start-stop sequences with limited overshoot. The shaft diameter is 6.35 mm, and the milled flat provides a reliable seat for set-screw couplings. The maximum winding temperature is 100 °C, so airflow or heatsinking must keep the coils below this threshold during extended duty cycles. For mechanical integration, the front flange uses a 2.625 in bolt circle that matches standard NEMA hardware.

The assembly weighs 1.23 kg, reducing reflected inertia to linear slides or belt drives. Bearings support axial thrust up to 44 N and radial loading to 66 N, enabling direct pulley or gear attachment without exceeding service life estimates. A protruding shaft length of 20.57 mm offers adequate engagement depth for clamps, collars, or couplings while keeping the overall package depth short. The shaft flat and mounting pattern support secure attachment with common power-transmission hardware in compact motion systems.
