The bonding can be automatically performed by E.D.C. systems (from the ACS320 / W system in a dedicated or integrated manner as a function in other testing systems for stators, coils, armatures, ...) using 2 or 3 generators in parallel (based on the product to be cemented and the cycle time).
The generators are selected by dimensioning them on the basis of the minimum and maximum diameter of the wire to be cemented and the relative current density.T
The bonding is achieved by injecting a current into the cementing winding supplied by electronic generators.
These generators can manage the cementation process in two distinct ways:
-
constant voltage
- constant current.
The bonding process is completely automatic and stops as soon as the desired temperature is reached. The temperature increasing curve can be viewed in real time on the system monitor.
In addition to a software control, the system normally also includes a special temperature sensor (pyrometer) which, independently of the software, immediately interrupts the power supply if the temperature exceeds the set safety threshold.
