Towards a Generation of Ironless Voice Coil Motors
2010Classical voice coil motors for linear displacements are often used in applications that require the force they exert to be a linear image of the current in the coil. However, these devices have drawbacks which are linked to the presence of iron and result in a non linear force. Therefore, this paper presents ironless motor structures.
