In 1999 Oriental Motor, Japan's largest manufacturer of AC and stepper motors, established a lead-free programme, with the first lead-free five-phase stepping motors being delivered at the end of 2001. Following this initial programme, Oriental Motor is now abandoning lead in the production of all current standard motors.
This early approach has helped the company address one of the primary requirements of the new RoHS directive far earlier than many other companies - indeed, many of its products were RoHS compliant well before the deadline in July 2006.
Oriental Motor now offers a wide range of RoHS-compliant products, including many of its standard AC motors, BLDC motors, stepper motors and drivers, electric actuators and cooling fans.
These products are marked with a RoHS label on the product box and, in the product catalogues, the specification is shown with the same mark. In somes cases the modifications also brought about technical improvements. The standard gears for AC motors, for example, now have a longer lifetime and remarkably reduced noise.
Depending on the series, the RoHS-compliant products are already available or will be introduced very soon. Customers are invited to consult Oriental Motor (UK) to confirm the RoHS-compliance of certain products.
RoHS, the European Union Directive 2002/95/EC, on the restriction of the use of certain hazardous substances in electrical and electronic equipment, applies to any equipment for use or import into an EU member state. The restricted substances include: Lead (Pb), Mercury (Hg), Hexavalent Chromium Cr (VI), Polybrominated biphenyls – PBB, Polybrominated diphenyl ethers - PBDE, and Cadmium (Cd). Electrical and electronic equipment must conform to 'a maximum concentration value of 0.1 per cent by weight in homogeneous materials for lead, mercury, hexavalent chromium, polybrominated biphenals (PBB) and polybrominated diphenyl ethers (PBDE) and 0.01 per cent by weight in homogeneous materials for cadmium.'
