In contrast with the vibration isolation regime, which requires active elements, the gravity compensation can be provided in a passive manner, i.e., without the need for power consumption. This paper presents two types of electromagnetic actuators whose design focuses on the passive gravity compensation and, furthermore, incorporate active elements which provide adjustability of their force response characteristics. The first actuator type mimics the behavior of a mechanical spring, i.e., positive and constant force stiffness, while the second type is characterized by a constant-force response, i.e., zero force stiffness. Two design solutions are obtained by means of aggressive output space-mapping optimization, and their respective characteristics are discussed.
The growing interest and activity in the field of sensor technologies requires a forum for rapid dissemination of important results: Sensor Letters is that forum. Sensor Letters offers scientists, engineers and medical experts timely, peer-reviewed research on sensor science and technology of the highest quality. Sensor Letters publish original rapid communications, full papers and timely state-of-the-art reviews encompassing the fundamental and applied research on sensor science and technology in all fields of science, engineering, and medicine. Highest priority will be given to short communications reporting important new scientific and technological findings.
