Hybrid Stepper Motors
ANTI-CORROSION
Thanks to special technology, the protective coating on the inside and outside of the engines is treated in such a way that these MOONS’ engines are resistant to rust and corrosion.
This allows these products to be used in aircraft, ships, cars, antennas, solar equipment, etc.
Plus
- Corrosion resistance
- Rust resistance
- NEMA sizes 17 – 23
- The motors are highly customisable for every application requirement
- Customisations available for wiring, shaft, winding, bearings, etc.
1 – Resonance zones are avoided
Compared to the 1.8° motor, when using the motor with 0.9° stepping angle, the working frequency of the motor is doubled and can be configured so that it does not fall into resonance zones, thus avoiding vibrations. As a result, the 0.9° stepper motor runs more smoothly and generates less noise.
2 – Customisation: Connection systems
You can choose between different types of connection; our motors can be fitted with an on-board connector or have outgoing cables of any length, with or without connector. The information below refers to STANDARD products, if you do not find the ideal configuration please contact us, all our components are customisable.
3 – Customisation: Drive shaft
It is possible to request customisations for the drive shaft and for the pulley or gear, if any. You can choose the MATERIAL, LENGTH and DIAMETER of the shaft. There are many possible configurations, for example the shaft can be: Cross-drilled – Single flat – Double flat – Keyed – Knurled – Notched – Hollow or with specific pulleys or sprockets.

4 – Customisations: Encoders, Reducers, Brakes and Drives
We do not sell components, but provide SOLUTIONS. Our stepper motors can be customised according to your needs; an ENCODER, a REDUCER, a BRAKE or a DRIVE can be fitted (versions with electronics already integrated in the motor are also available, visit the page). If you have a specific requirement, do not hesitate to contact us!

Electric motors used outdoors are susceptible to sometimes extreme temperatures and moisture accumulation. These factors cause internal corrosion, which can lead to component failure.
Traditionally, attempts were made to solve the problem by sealing the motor to prevent moisture from reaching internal components.
Unfortunately, it has been noted that shaft and terminal seals can only delay the onset of the phenomenon, but not stop the appearance of moisture in the engine. Furthermore, the presence of shaft seals causes a loss of 3 to 15 per cent of torque due to friction.
Today, a new approach is used to prevent corrosion and early failure by using a system of effective linings. MOONS’ new technology applies a protective coating to EVERY SURFACE AND STRUCTURE INSIDE AND OUTSIDE THE MOTOR; including the rotor, stator and housing. All surfaces that could potentially rust are therefore covered.

The experiment
An experiment was conducted to test MOONS’ engines with anti-corrosion coatings, and American Standard MIL-STD-202G salt spray was used.
The resistance of the new MOONS’ coatings was tested in an accelerated corrosion test with military standards.
Conventional engine
96 hours after the salt spray test, extensive corrosion can be seen, the rotor is blocked and the motor is no longer able to run.
MOONS’ anti-corrosion motor
A full 240 hours after exposure to salt spray, the motor is completely normal and runs smoothly.
