Description
Oriental Motor Vexta PH268-21B 2-Phase Stepper NEMA23 Double Shaft 5.4V 1.5A
The Oriental Motor Vexta PH268-21B is a NEMA 23 frame, 2-phase bipolar stepping motor offering precise 1.8°-per-step angular resolution. It features a double-ended shaft design — a shaft extends from both the front and rear of the motor body — giving system designers flexible coupling and encoder-mounting options without a separate adapter. The motor is driven at 5.4V DC at 1.5A per phase and is manufactured in Japan by Oriental Motor Co., Ltd. under their well-established Vexta line.

Applications
NEMA 23 2-phase stepping motors like the Vexta PH268-21B are standard motion-control components used across a wide range of precision positioning applications. They are commonly found in CNC machines, laser cutters and engravers, 3D printers, laboratory automation equipment, pick-and-place systems, medical instrumentation, and general-purpose robotics. The 1.8°/step resolution (200 steps/rev) makes them well-suited to open-loop positioning systems where predictable, repeatable motion is needed without encoder feedback. The double-shaft design is particularly useful when mounting an optical encoder or tachometer on the rear shaft while driving the load from the front. Oriental Motor's Vexta series has been a trusted name in stepping motor technology since the 1970s, and the PH268 series motors are compatible with a broad range of standard 2-phase stepper drivers, including chopper-type constant-current drivers commonly used in modern CNC and automation controllers.
This Oriental Motor Vexta PH268-21B 2-phase NEMA23 stepping motor is in good used condition. Both output shafts are present and undamaged, and the multi-color flying leads are intact with no visible fraying or damage. The black motor body shows minor surface wear consistent with prior use, and the aluminum mounting flange is in good shape. It was pulled from a working environment where it was previously in service. Please view our photo set and contact us if you have any questions.
