The T High Torque Motors series is a two-phase stepper motor family that covers both legacy T-frame models and newer NEMA 23 variants.
They have a step angel of 1.8° In the NEMA 23 group, the listed nominal holding torque classes step from 0.52 N·m to 2.68 N·m, and are rated for a maximum speed of 3000 RPM. Those NEMA 23 models share a 56.9 mm motor width and 20.6 mm shaft length. The series includes both parallel and series winding versions which change rated current, inductance, and winding resistance while keeping the same torque class within a given frame family. Standard options include connector, rear-shaft, and encoder availability with IP40 maximum sealing and CE/UL agency ratings, while the larger T-frame entries also specify continuous stall torque levels up to 8.8 N·m and a 100 °C maximum winding temperature.
