LCS laminations are manufactured for industries that require adherence to demanding specifications and certifications for raw materials, manufacturing processes, and thermal treating.

LCS can produce electrical laminations and lamination segments from 1/2 inch thru 24-inch diameters utilizing punch presses from 3 to 330 tons. Quantities of several thousand, several hundred thousand through several million are routinely processed and fit our capabilities and our facility’s automation well.

Cobalt and Nickel alloys, Silicon steels (M15-M45), and cold rolled motor lam are commonly utilized to meet customers’ program requirements. Insulator lamination materials such as Nomex, Delrin, Fiberglass, Rubber, and PTFE can be processed as well.

To get all this done LCS uses compound and progressive tooling technologies built and maintained in-house. LCS also utilizes laser cutting for smaller prototype/development quantities.

Custom-Motor-Laminations

What Are Motor Laminations?

Motor laminations are thin component parts that make up the cores of electric motors. Once manufactured, depending on the requirements of the end application, they would be bonded or welded together to form the core. There are several grades of electrical steel available for the manufacture of laminations. The selection of the electrical steel influences the motor efficiency, weight and cost.

How Are Motor Laminations Made?

Motor laminations are made from thin coils of electrical steel that are run through automated press lines into large presses that contain progressive or compound tooling that stamp the motor laminations from the steel. Laser cutting can also be utilized for start up and immediate lamination needs.

Our Motor Lamination Capabilities

LCS Company produces electrical laminations and lamination segments ranging from 1/2 inch to 20 inches in diameters and quantities ranging from several thousand to several million.

Different Types of Motor Lamination Materials

The materials used to produce motor laminations vary greatly depending on the motor’s end-use application. The material selected has a significant influence on the unit’s performance, as well as cost, size, and weight.

Some of the most commonly used materials that are involved in the production of motor lamination include:

  • Cobalt alloys. Delivering improved resistance to wear, corrosion, and heat, cobalt alloys are most commonly used in applications that require high flux density without saturation.
  • Nickel alloys. Nickel alloys feature high permeability at low to moderate inductions as well as low core losses. Nickel alloys require an annealing cycle with added surface insulation.
  • Electrical steel. This material features excellent electrical conductivity and facilitates improved performance. Silicon steels are available in several grades and thicknesses.
  • Thin-gauge electrical steel. Thin-gauge electrical steel is ideally suited for applications with energy efficiency and high-performance requirements
  • Transformer steel. A form of electrical steel, transformer steel is an electrical steel that features magnetic properties specifically suited to non rotation devices.
