Various measurement hardware and inspection equipment|Impulse winding tester


Coil tester

Comprehensive testing machine
Automatic Winding Testing Machine AWX-05S

This equipment is a system which does several electric characteristic tests, such as Armature and Stator coils. It is a system which performs an automatic test and judge according to the set-up parameters, and anyone can perform quality test judgment easily by desorbing a work.
Moreover, an impulse test is efficient and does the electric examination of the winding state by not destroying the item.
It is inductance and Q which the damped oscillatory wave form generated in a transient phenomenon waveform, i.e., coil, and when there are number of turns difference in a coil, a core, the difference in the material, etc. can judge it simultaneously.
That is, almost all characters required as a quality of winding can be inspected very much in a short time.


Reduction of Cost
High Speed Inspection
Improved durability


Armature coil automatic testing machine AWX-05A

In this system, welding resistance (fusing resistance) is judged by increasing the accuracy of resistance measurement . As for test item, DC resistance, fusing resistance, impulse test, AC withstand voltage, insulation resistance is performed. It can measure up to 32 poles (DC resistance, impulse).

Stator coil automatic testing machine AWX-05S

As for measurement item, DC resistance, impulse test, AC withstand voltage, insulation resistance. It can measure up to 6 circuits (DC resistance, impulse, AC withstand voltage).

■Optional rotation test, 2 station test stand and safety cover for jig parts are also available.
