PURPOSE:To easily detect slacks of a stator winding, by attracting coil ends toward the inner diameter side with a spring strength measuring device making application of pliers, and by detecting spring strength quantitatively in terms of its attracting force and displacement quantity. CONSTITUTION:A stator core 1 is provided with confronting sections 1a-1b in the diameter direction, and with coil end sections 2a-2b confronted with each other in the direction of the diameter of a stator winding protruded from the slot of the core 1. A pliers-formed spring-strength-measuring device 3 is organized with chuck sections 4a-4b, elastic arms 6a-6b, handles 11a-11b, and a first and a second dial gauges 7, 9, and is provided with wires 12a-12b for connecting the chuck sections 4a-4b to the coil ends 2a-2b. Then, by measuring spring strength with pliers application, everybody can detect slacks of the stator winding quantitatively without the need of special skill on work. |
