Motor laminations are thin sheets of steel stamped in the shape of a rotor or stator. These laminations are then stacked to form the core of an electric motor’s rotor and stator. Lamination stacks minimize heat and energy loss, enabling efficient devices with improved performance and better control over their magnetic properties. We will explore…

Effective prototype motor laminations depend on selecting a material based on the motor’s exact performance characteristics. Heat, corrosion, magnetic fields, and external operating conditions are just some of the considerations bearing a significant impact on lamination materials. Cost and lead time also affect the production feasibility of certain metals. Nickel, cobalt, and silicon steel are…

The United States Department of Labor Machine One course from Camden County College focuses on CNC, manual, mill, and lathe machining. It involves 2,000 hours of on-the-job training and online academic Related Technical Training (RTI). After completing the RTI, apprentices receive a 13-credit Academic Certificate in Precision Machining Technology (PMT). Thomson Lamination Company, Inc. (TLC®)…

Industries ranging from aerospace to medical, automotive, and many others rely on precision metal stamping services from Thomson Lamination Company.…

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…

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…

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…

Synchronous Motor vs. Induction Motor Electric motors are pieces of equipment used for converting electricity into mechanical energy. They use electromagnetism to operate, which facilitates the interaction between an electric current and the magnetic field of the motor. This interaction generates torque in a wire winding that causes the motor shaft to spin. Electric motors are…

Brushless vs Brushed Electrical DC Motors Electric motors convert electricity into mechanical energy. Most electric motors operate through an interaction between the motor’s magnetic field and winding alternating current (AC) or direct current (DC). Electric motors are used in a wide variety of applications, from fans and power tools to appliances and electric vehicles. DC…
