As engineers, finding the right solution for prototype motor stator lamination stacks can be a challenge. Laser cutting stator laminations offer a range of benefits over traditional methods.
In this blog, we’ll discuss laser cutting stator lamination, its advantages and disadvantages, and how it can help you create successful prototypes. This information lets you know laser cutting is the right choice for your prototype project.
What is laser cutting motor lamination?
Laser cutting is suitable for prototyping motor lamination. Laser cutting motor lamination is a process that uses a laser to precisely cut thin sheets of metal into the precise shape required for use in electric motors. The sheets are coated with a special insulating material and then cut using a high-powered laser beam directed by a computer-controlled system.
This process allows for the exact cutting and shaping of the metal, ensuring that the resulting laminations are perfectly uniform and defects-free.
Advantages of laser cutting stator lamination
One of the key advantages of laser cutting is its precision, which allows for intricate designs and tight tolerances that result in higher performance and efficiency of the motor. This precision also makes it possible to create complex shapes and patterns that were previously impossible with other cutting methods.
Another advantage of laser cutting is its speed, allowing for faster production times and a shorter time to market for products.
Laser cutting is a superior choice for manufacturers looking to prototype stator laminations.
Different Materials Available For Stator Lamination
Motor stator laminations come in various shapes and sizes. The materials include silicon steel, steel alloys, and other common metals.
These laminations are usually lightweight yet durable enough to withstand extreme conditions in many industrial applications.
Silicon Steel
Silicon steel, also known as electrical steel, is steel with silicon added to it. Adding silicon to steel increases its electrical resistance, improves the ability of magnetic fields to penetrate it, and reduces the steel’s hysteresis loss.
Metallic soft magnetic materials
Another is metallic soft magnetic materials. Ferrite is a soft magnetic material with iron oxide as the primary raw material. The iron core is generally made of a silicon steel sheet. Silicon steel is silicon-containing steel, and the general silicon content is 0.8 ~ 4.8%.
Electromagnetic steel plate
Another is electromagnetic steel. This is currently the most used motor core material. It has good magnetic characteristics, easy processing, and a low price.

FAQs
What is motor stator lamination?
Motor stator lamination is a type of electromagnetic material that create the stator, which is the stationary part of an electric motor.
The lamination consists of thin sheets of high-grade steel stacked together and insulated with a thin layer of insulating material. It helps to reduce the number of eddy currents that can be created within the motor, which can cause losses in performance and efficiency.
These losses can add up quickly, so using good-quality lamination is important to get the most out of your motor.
Motor stator lamination also helps to reduce vibration and noise while improving motor performance, making it a key component in any electric motor design.
Without good-quality lamination, motors would not be able to run as efficiently or produce as much power as they do today.
How are the stator laminations joined together?
A few methods can join stator laminations together.
One option is to use rivets, small metal fasteners inserted through holes in the stator and then secured on the other side.
Another option is to use glue, which can be applied to the surfaces of the laminations to hold them together.
Finally, welding can also join the stator laminations together. This process involves applying heat to the metal surfaces of the laminations, which causes them to melt and fuse.
Each method has its advantages and disadvantages, and the choice of which one to use will depend on various factors, including the size and shape of the stator, and the materials.
What is the lamination thickness used in the induction motor’s stator?
The thickness of laminations of an induction motor is usually between 0.35mm and 0.5mm. Most motors use a thickness of 0.4mm.
This thickness ensures that the stator can handle the magnetic forces generated by the rotor during the operation of the motor. While also ensuring that it will not experience any structural failure due to excessive heat or vibration.
The lamination material is usually silicon steel sheets coated with a thin insulation layer to prevent short-circuiting between layers.
While this thickness may vary depending on the type and size of the motor being used. Ensuring that the lamination material chosen can withstand thermal and mechanical stresses over extended periods is important.
