VCM F1 adopts the traditional voice coil motor design scheme, linear motor structure is simple, high stability. Using high precision grating ruler as position feedback, position resolution accuracy is 25 bits. Digital encoder technology greatly improves positioning accuracy, in addition to extremely low noise, excellent linearity and minimal drift. VCM F1 is a digital processing driver technology based on FPGA. The digital driver has excellent anti-interference ability and excellent dynamic performance. In addition, it has good waterproof and dustproof performance.
