Purchase now: Wittenstein NP015S-MF1-7-1C1-1S Gearbox
Purchase now: Atlantech Drives provides you the Wittenstein Alpha NP015S-MF1-7-1C1-1S, a versatile **Planetary Gearbox** from the **alpha Basic Line (NP Series)**. This unit features the «Universal» reduction **Ratio of 7:1**, which offers an excellent compromise between speed reduction and torque multiplication. Fitting the compact **Size 015** frame, this gearbox provides significantly higher power density and torsional stiffness compared to the older CP series, making it ideal for dynamic pick-and-place arms and packaging actuators.
Technical Specifications and Interface 1C1
The NP015S utilizes a single-stage gear set with high-efficiency spur gearing (> 97%). The suffix **»-1C1″** is the **Motor Interface Code**. It defines the specific adapter plate geometry (Pilot, Bolt Circle) and the input clamping hub diameter. You must verify that your servo motor matches the Wittenstein «1C1″ specification to ensure a concentric fit. The output shaft is a **»1S» Smooth Shaft** (non-keyed), designed for zero-backlash force transmission when used with clamping couplings.

Expert Tips: The «Ratio 7» Sweet Spot
Why choose 7:1? Expert Tip: A ratio of 7:1 is often preferred in automation because it is a prime number (good for gear wear distribution) and it allows a 3000 RPM motor to output approx 428 RPM. This speed is perfect for driving timing belts in linear modules without needing excessively large pulleys. It keeps the reflected inertia low while maintaining high throughput.
Frequently Asked Questions (FAQs)
Q: What is the difference between NP and CP?
A: The NP series allows for higher maximum torques and input speeds than the legacy CP series, thanks to improved internal bearing arrangements and gear geometry.
Q: Can I use a keyed coupling?
A: No, this unit has a «1S» Smooth shaft. You must use a compression/clamping style coupling. Keyways are not recommended for high-dynamic reversing loads as they develop play over time.
