In 1997, a new concept was developed by AEM Cores (Pty) Ltd, using a mixture of the old Distributed Gap Core, C cores and stamped laminations. This new development was a radical departure from all of the traditional methods used before. This innovative concept allows complete freedom in transformer design because unrestricted core sizes are available. We have called this core a “Jencore” after the name of the founder, Mr. Jenkinson.
