A new type of energy saving,high sensitivity rectangular deflection coil,used in 19 inch 110° deflection cathode ray tube (CRT),has been successfully developed.The compact structure of the coil greatly simplified the calculation and optimization of the complicated 3D electromagnetic field.Moreover the results of the existing optimization of the rotational symmetric deflection coil can still be used.As a result,much design time can be saved.The excellent deflection performance of the rectangular deflection coil newly designed indicates that this design method is also feasible in non rotational symmetric rectangular coil design and in solving quite a few electromagnetic problems.
