  • Method and system for evaluating core stack pressure
    Patent number: 6794884
    Abstract: A method for evaluating core stack pressure includes: positioning a magnetic yoke near the core, the magnetic yoke being wound by an excitation winding; supplying current to the excitation winding to inject magnetic flux into the core; measuring a signal resulting from the injected magnetic flux; and using the measured signal to evaluate the core stack pressure. A system for implementing the method includes the magnetic yoke; a current supply for supplying the current; a sensor for measuring the signal; and a computer for using the measured signal to evaluate core stack pressure.
