Overview
The Oriental Motor 4TK10GN-AUL is a pinion shaft torque motor rated at 10W (1/75HP) output. Designed for single-phase 110/115VAC operation at 60Hz, this discontinued model maintains the high starting torque and voltage-controlled speed characteristics that make torque motors ideal for precision positioning and low-speed applications. The motor features a compact 3.15-inch frame and comes with 12-inch lead wires (UL Style 3271, AWG 20) for straightforward installation.
