PURPOSE:To improve the precision of inspection by a method wherein whether the state of assembly of stator coils is normal or not is decided based on the outputs of a plurality of magnetic sensors arranged in a jig for inspection. CONSTITUTION:The respective state of assembly of main coils 3-6 and auxiliary coils 7-10 is detected by hall elements 12-19. Based on detection signals therefrom, whether the state of assembly of stator coils is normal or not is decided by a decision circuit 20 comprising AND gates 25, 26, 31 and 32, a memory unit 33 for the main coils, a memory unit 34 for the auxiliary coils, etc. The result of the decision is indicated by a lamp 38. By this constitution, an improvement in the precision of inspection, the reduction of a time required for inspection, etc. can be realized. |
