Paper Abstract

The high rotational speed standard device based on brushless DC coreless micro motor and FPGA technology for highaccuracy rotational speed control was investigated and established, with resolution of 1 r/min in the measurement range of 40000 r/min to 100000 r/min. The expanded calibration uncertainty of this standard device is 1×10-5, k=3 The structure of the device and key technology involved were described.The dual closed-loop control solution was explained. The calibration results were provided.This high rotational speed standard device is used as an important working standard for the feasible traceability of high-precision optical tachometers and rotational speed measuring instruments at measurement range above 40000 r/min.
