Geared motors and brake motors with additional protection
Lenze is now offering a three-level system of surface and corrosion protection to ensure its geared motors and geared motors perform reliably in outdoor installations and environments with high humidity or atmospheric contamination. Available as an option on the G-motion geared motors and geared brake motors, the new protection system includes an optimised multi-layer paint finish plus other supporting measures. While Lenze geared motors with the standard protective measures are resistant to oil, dirt and moisture, the new option is said to suit almost all industrial applications.
The three levels of protection offer customers an easy choice to achieve a long and trouble-free life. The level OKS-S suits indoor heated environments with humidity levels of up to 90 per cent. Here Lenze applies a two-pack polyurethane paint finish with excellent colour stability and weather resistance suiting corrosion category C1 of the standard EN ISO 12944-2 (Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 2: Classification of environments). Corrosion protection is applied to the output shaft, and standard brakes, blowers and encoders are optional. Resistance to condensation and salt spray has been proven by testing to the relevant standards.
At the next level, the higher OKS-M paint specification is suitable for use in covered outdoor areas with up to 95 per cent humidity. The highest level, OKS-L, suits use outdoors or in environments with high ambient temperatures, or atmospheric pollution from oils, solvents and acids. Here the paint finish is upgraded and applied to areas not normally coated - for example, inside the fan cowl and the motor B-shield. Fixing screws are zinc coated and cable glands incorporate seal rings. Optional are a corrosion-resistant brake with seals and an IP65 encoder. The OKS-L level meets category C3 of EN ISO 12944-2.
The new Lenze system for surface and corrosion protection is available for motors and geared motors from 60W up to 45kW. Customers gain the assurance of long-term and reliable operation based on these three well-defined protection levels.
