Abstract: The analysis and optimization of static magnetic field in the electromagnetic force measuring system, the position control method of electrified coil and the calibration method with improved linearity are introduced. The Maxwell 3Dis used to do simulation, a relatively optimized magnetic density and magnetic uniformity are obtained. And the accuracy of electro magnetic force measurement is improved by controlling the position of the electrified coil in the magnetic field as well as using the piecewise linear differential technology. A test device is constructed, and the comparison with the test data shows that good results have been achieved in improving the accuracy of electromagnetic force measurement.

Key words: Electromagnetic force measurement system, Magnetic induction intensity , Distribution , Position control
