MAGNETIC ALIGNMENT SYSTEM AND ALIGNMENT METHOD THEREFOR

摘要

A magnetic alignment system, comprising a magnetic steel array (10), a motor rotor (20), a fixed tooling (30) and a force sensor (40). The motor rotor (20) is located above the magnetic steel array (10), and is connected to the fixed tooling (30) fixed at a relative position of the magnetic steel array (10) through the force sensor (40). By way of transforming the angle of a three-phase current introduced in a certain three-phase coil of the motor rotor (20) within a magnetic alignment angle cycle, and measuring an output value of the coil assembly by the force sensor (40), the magnetic alignment angle of the coil assembly can be obtained according to the angle of the three-phase current corresponding to the maximum output value of the coil assembly.
