Product Description:

The T22NRLC-LNN-NS-00 is a hybrid stepper motor produced by Pacific Scientific within the T High Torque Motors series. This two-phase unit converts digital pulse trains from an indexer or motion controller into incremental shaft rotation. It can position conveyors, small gantries, or metering pumps without feedback devices. The motor is intended for open-loop motion systems that rely on commanded step counts to set position and speed.

The motor advances one full step for every electrical transition, and its angular resolution is 1.8°; this means 200 full steps complete one mechanical revolution. A holding capability of 1.98 N·m allows the shaft to resist static loads when the windings are energized, helping prevent back-driving in vertical axes. Each phase draws 0.46 A DC, a low current that minimizes drive-stage heat generation in compact control cabinets. Winding inductance of 209 mH shapes the current rise time, so rapid pulse rates may require higher bus voltage to sustain torque at speed. Copper resistance measured at 40 °C is 41.4 Ω, and that value contributes to steady-state copper loss and temperature rise during continuous stall duty. The motor also has a detent torque of 0.042 N·m and a 2-phase construction that accepts standard full-step or half-step excitation patterns.

The shaft tolerates an axial force of 111 N and a radial side load of 67 N, so couplings or pulleys can be mounted without exceeding bearing limits. A rotor inertia of 0.0000395 kg·m² permits quick acceleration yet stores enough kinetic energy for smooth microstepping. Overall length is 77.7 mm, while the width is 56.9 mm and the housing mass is 1 kg. The 6.35 mm diameter shaft extends 20.6 mm beyond the front face, providing room for set-screw hubs while maintaining the nominal holding torque envelope. Its compact body also helps when several axes must be installed close together on a machine frame.
