Stacks built with punched laminations can have a lot of quality issues. Even though the lamination material is tested in sheet format before any process, that alone is not sufficient to guarantee good quality stators. Wear and tear of the punch, bad welding, bad insulating coating in annealing add to the magnetic losses in the stator. It is always advisable to test the stator core in it's final format before winding to ensure good quality throughout the production batch.

Incoming material inspection can be very useful where strict quality standards are maintained. It saves a lot of processing cost since lossy material is inspected at the entry level before it goes to production level. Epstein Stack testing is one of the oldest and widely used methods for electrical sheet testing.

In the measurement of magnetic fields by means of Hall probes or measuring coils it is necessary to calibrate the instruments in a known magnetic field. Our standard field coil according to Helmholtzenables to production of a magnetic field calculable with high accuracy from the dimensions and the amperage. In series arrangement with an accurate ammeter field strengths of up to 800A/cm are produced. The dield room accessible both in axial and radial direction. Helmholtz coils with fluxmeters are also useful in testing of magnets. Helmholtz coils give repeatable results as against the search coils due to which the magnets can be compared with more accuracy for their total flux and in turn their quality. Field Generating and Field Detecting Helmholtz coils are designed as per user specifications.

Many times it is requires to study the magnetic field profile of the 2D or 3D surface to estimate the performance of the magnetic device. The field pattern is measured by sensors and very precise mechanical arrangement. The spacing between two points of measurement can be as low as a few microns. This precise measurements can confirm the quality of performance of any device.

Zero field cavities generate a zero magnetic field in an air gap. They are mainly used to calibrate hall probes for their zero scale value of output for the magnetic field strength H or the magnetic flux density B they measure. For example Gaussmeters can be calibrated by using Zero Field Cavity.

Reference magnets generate a homogeneous magnetic field in an air gap. They are mainly used to calibrate hall probes for their full scale value of output for the magnetic field strength H or the magnetic flux density B they measure. For example Gaussmeters can be calibrated by using reference magnets.

Flux meter has been the established standard for the measurement of magnetic flux density for determining total flux in a magnet or magnetic assembly. Its use was curtailed except in a few specialized areas because of many factors such as the difficulty in setting up light beam flux meter or ballistic galvanometers, limitations on the ohmic resistance of search coils, the requirement of some degree of operator skill in reading the flux meter etc. The development of the integrating type Digital Flux meter has virtually cancelled the hitherto negative aspects of fluxmeterology and has found a broad niche for many magnetic measurement applications.
