There are specifications for large electric machines and drives that dictate how the noises and vibrations they produce should be measured and assessed. On its own, a micro-drive is considered to be ultra-silent due to its small dimensions, while its vibrations are generally not seen as troublesome. Such drives are therefore generally first noticed within the context of the device to which they are attached or installed in and often only then subjectively assessed. Many engineers and technicians regularly have to deal with acoustical issues stemming from the electrical micro-drives installed in the products they have developed.
The Faulhaber reference book ‘Vibrations and sounds of electric micro-drives’, now available in English, provides assistance to approaching vibration and acoustics related issues. Furthermore, provides a common basis for discussing sound-related issues and act as a foundation for constructive communication between customers and suppliers. The book is based on practical industrial experience and is therefore better classified as a practical handbook than an instructional textbook.
