Description

An Indexed Lamination Stack is a precision-engineered component consisting of multiple thin electrical steel sheets arranged in a specific angular orientation. Unlike standard lamination stacks, indexed stacks feature carefully positioned laminations where each layer is rotated at a precise angle relative to adjacent layers. This indexed arrangement minimizes magnetic flux variations and reduces cogging torque in electric motors, resulting in smoother operation and improved efficiency. The precise alignment of lamination slots and teeth across the stack helps eliminate harmonic distortion while optimizing magnetic circuit performance. Commonly used in high-performance motors for automotive applications, power tools, and precision equipment, indexed lamination stacks represent an advanced manufacturing approach that delivers superior electromagnetic performance while reducing noise, vibration, and energy losses.
