Miniature linear motors for pharmaceutical and medical industry

One of the advantages of the NLH series is its compactness with flange dimensions beginning from 15x34mm till 35x63mm. The linear motor is composed of a high performance three phase winding, an integrated encoder SIN/COS 1Vpp and a rod in AISI 304 stainless steel. The NLH series, composed of 6 different types, has an excellent performance and 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 thickness ranging from 10 to 200µ, 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’s unremovable.

The G.H.A.® process (Golden Hard Anodizing) is patented (Patent No. EP1207220).

The advantages of the G.H.A. process are numerous:

• 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 in the medical industry.
