Purchase now: Wittenstein NP015S-MF1-10-1E1-1S Gearbox
Purchase now: Atlantech Drives provides you the Wittenstein Alpha NP015S-MF1-10-1E1-1S, a high-efficiency **Planetary Gearbox** from the versatile **alpha Basic Line (NP Series)**. This component is designed for precise motion control applications requiring a reduction ratio of **10:1**. The NP015S frame size offers an exceptional balance of torque density and compact dimensions, making it the ideal choice for small gantry systems, packaging actuators, and medical automation equipment.
Technical Specifications and Interface 1E1
The unit features a single-stage planetary mechanism («MF1″) that delivers high torsional stiffness. The most critical specification for installation is the **»-1E1″ Motor Interface Code**. This code dictates the precise geometry of the input adapter plate (Pilot diameter, Bolt Circle Diameter) and the clamping hub (Input shaft diameter). You must verify that your servo motor’s flange dimensions match the Wittenstein «E» standard for Size 015. The output shaft is a **»1S» Smooth Shaft** (non-keyed), which is the industry standard for creating a zero-backlash friction connection with the load.

Expert Tips: Smooth Shaft Coupling
Why no keyway? Expert Tip: The «1S» suffix indicates a smooth output shaft. In high-precision servo applications, keyways are actually a disadvantage because the key can wear down during reversing cycles, creating «play» or mechanical backlash. A smooth shaft, when used with a proper clamping element (shrink disc or clamping hub), provides a 360-degree friction grip that never loosens and transmits torque with zero backlash. Ensure your pulley or coupling has a clamping style hub.
Frequently Asked Questions (FAQs)
Q: What happens if I mount a «1B1» motor to this «1E1» gearbox?
A: It will not fit. The bolt holes will likely not align, or the centering pilot will be the wrong size, preventing the motor from seating flat against the gearbox.
Q: Is the NP series better than the CP?
A: Yes, the NP (New Planetary) is the successor to the CP. It generally offers higher torque ratings and better bearing life in a similar or smaller footprint.
