摘要
The invention relates to a method and an apparatus for use in the assembly of an axial-flux permanent-magnet synchronous machine. The machine comprises a stator (2) provided with windings (1) and a rotor (4) provided with permanent magnets. An air gap (5) being provided between the stator and rotor. A known interdependence of the magnetic attraction between the stator (2) and the rotor (4) and the magnitude of the air gap is determined beforehand. Based on this interdependence, a target value of magnetic attraction corresponding to the target value of the air gap is determined. When the machine is being assembled, the rotor (4) and stator (2) are moved axially with respect to each other by means of a hoisting device (7) to adjust the air gap (5) towards the aforesaid predetermined target value. During this movement, the magnetic attraction between the stator (2) and rotor (4) is measured and compared to the above- mentioned target value of magnetic attraction. After the magnetic attraction has reached its target value, which corresponds to the target value of the air gap, the mutual position of the rotor and stator is locked.
