Optimal control of a voice-coil-motor with Coulombic friction
2008 47th IEEE Conference on Decision and Control, 2008The voice-coil-motor is a widely used mechatronic device, which represents a typical electrodynamic actuator for machine tool axes, bonding machines and hydraulic/pneumatic valve drives. One principal task consists in steering the system precisely to a prescribed target in minimal time or with minimal energy.

A Specially Arranged Halbach Structure for Voice Coil Motors
2020 3rd International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE), 2020This paper proposes a special Halbach structure for the magnetic circuit design of voice coil motors(VCM). The permanent magnets arranged by the special Halbach array are stators and the coils are movers. After calculation and finite element software Ansoft Maxwell simulation, the results show that the improved structure not only provides greater ...
