Abstract :
IN laminated-core structures for transformers and rotating machines the need for adequate interlamination resistance becomes more necessary as the core structure increases in size. Where considerable pressures are exerted on the core laminations, a safe value of interlamination resistance must be maintained to prevent the stray losses in the core from becoming excessive. A method for determination of the minimum interlamination resistance required in terms of the core and its operating conditions, for any degree of permissible stray loss, is developed herein, resulting in a simple equation.
