NILAB's miniature tubular linear motors are a complete solution for the pharmaceutical and medical industry, and for all kinds of automatic machines in general.
One of the advantages of the NLH series is its compactness: flange dimensions from 15×34 mm to 35×63 mm. The linear motor is composed of a high-performance three-phase winding, an integrated SIN/COS 1Vpp encoder, and a rod in AISI 304 stainless steel. The NLH series, consisting of 6 different types, offers an excellent performance-to-dimension ratio. The force range starts from 0.6 N up to 20 N of continuous force, with peak forces 6 times these values. The standard power supply of the drive is 24/48 VDC.
The difference between the NL series and the NLH series is the G.H.A.®-coating.
It is one of the most recent and innovative technologies applicable to the surface of all aluminium-base alloys. The surface is treated by a special anodic oxidation, with a thickness ranging from 10 to 200 µm, followed by the sealing of the micro-porosities through silver ions (Ag+). The anodic oxidation of aluminium-base alloys is the safest protection treatment, because it is unremovable.
The G.H.A.® process (Golden Hard Anodizing) is patented (Patent No. EP1207220).
The advantages of the G.H.A. process are numerous:
| Item |
| Highest corrosion resistance |
| High antibacterial capacity and anti-mould (antibacterial) |
| Antistatic capacity |
| Thermal conductivity |
| Heat resistance |
| Resistance to consumption |
| Melting temperature: 2100 °C |
| Hardness: 500–600 HV |
| Suitable for direct contact with food |
Therefore, aluminium alloys with the G.H.A.®-coating are considered an excellent alternative to expensive metals such as stainless steel or titanium alloys.
The miniature tubular linear motors of the NLH series with the innovative G.H.A.®-coating are specially designed for applications in the food, pharma, and medical industries.
