What Are Stator Core Laminations?

In electric motors, the cores of rotors and stators consist of motor laminations. A motor lamination is a thin sheet of metal usually bonded, welded, or stacked together to form several durable layers. They reduce eddy current losses because they use multiple individual metal pieces instead of one solid metal piece. Here you’ll learn more […]

How to Choose Material for Lamination Stack Prototyping

Motor laminations, or lam stacks, are thin sheets of metal that are stacked on top of one another and bonded together for use in rotors, transformers, and more. This stacking process allows for less eddy current loss when compared to using a solid piece of metal. There are a variety of materials that can be […]

What is the Difference Between Tempering and Annealing?

Tempering and annealing processes both apply heat to metal to modify its composition without altering its shape. Heat treating metal can make it more ductile, easier to work with, less brittle, and overall, more reliable for manufacturing and specialized applications. The key difference between the two heat treatments comes down to the cooling method. Tempering […]
