Ken et al In some of our products the only electrical components are induction motors. Thus we commissioned a statement as to whether these may be considered benign under the EMC directive. The relevant part of the report is as follows:
Benign components and equipment are exempt from the requirements of the EMC Directive. The general definition of such equipment is that it is passive by nature and incapable of generating an emission disturbance conducted on power lines or radiated into the environment or to be susceptible to disturbances coupled through cables or radiated directly to the device. Generally benign devices will be relatively simple and consist of passive components such as resistors and capacitors and will contain no active electronic devices or high frequency converters, oscillators or clock sources. Transformers are specifically exempt and in the guidance notes to the EMC Directive, induction motors are exempt. You should obtain a similar assessment of your products by a competent body such as ERA http://www.era.co.uk/ . I don't work for them - so I think I am allowed to promote them!
