Stacking Motor Core Use Cleating Technology
The cleating process is one of the ways of stacking and bonding the stator of our motor and has minimal impact on core loss.
We depend on the desired core length; the motor stator core lamination is performed with galvanized tape /CR tape up to 2 mm thick to stacks.
These motor cores are assembled by pressing steel strips into notches around the laminations. The cleating is usually folded over the end of the stator core.
Clamping notches vary from 2 to 16 per stator, depending on the electric motor size. The location of the cleat notches should be in line with a lamination tooth or slot opening.
On large stators with many splints, they must be evenly distributed around the perimeter of the stator and are always two notches 18 degrees apart.
Materials Used In Cleating Manufacturing
Our material choice for cleats depends on mechanical strength, corrosion resistance, and lamination compatibility. Common materials used for cleats include:
Cold-Rolled Steel (CR Steel): Due to their strength, durability, and ease of fabrication using Cold-rolled steel strips. They provide the necessary mechanical reinforcement to the laminations.
Galvanized Steel: Galvanized steel coats a layer of zinc to enhance its corrosion resistance. It is commonly used when both strength and corrosion protection are required.
Non-Ferrous Alloys: non-ferrous alloys like aluminum or copper may be used as cleats for specific applications. These materials offer different thermal and electrical properties compared to steel.
Advantages Of Cleating Motor Laminations Stacking
Structural Integrity
Cleating reinforces the core assembly by introducing metal cleats between laminations. This additional support minimizes the risk of laminations shifting during operation.
Improved Heat Dissipation
The introduction of cleats creates conditions for heat to escape from the stator core.
Reduce core loss
Cleating offers the advantage of improved dimensional stability without significantly increasing core loss. This means that the motor’s energy efficiency is not compromised.
Maintenance of Electrical Clearance
While careful design and implementation, maintain electrical clearances. This prevents any adverse effects on the electrical performance of the motor.
Quieter Operation
Cleated stator laminations exhibit reduced operational vibrations and noise. The stabilization provided by the cleats reduces undesirable resonances within the core, resulting in quieter and smoother motor operation.
Compatibility
Cleating is suitable for different sizes of motors. The number and placement of cleats can be adjusted to match the specific requirements of different motor designs and applications.
Application Of Cleating Motor Stator And Rotor Core
Our cleating stator laminations are a versatile technique and find application across various industries and sectors.

HVAC Systems: Heating, ventilation, and air conditioning systems benefit from cleated stator laminations.
Electric Vehicles: Cleated stator laminations are vital for electric vehicles (EVs) due to their compact and high-performance motor requirements.
Renewable Energy: Cleated stator laminations play a role in renewable energy systems, such as wind turbines and solar tracking systems.
Aerospace and Defense: Cleating ensures that motors used in aircraft, drones, and defense equipment can withstand extreme conditions and maintain efficiency.
Cleating Laminations Stacks FAQs
Cleated stator laminated offers enhanced benefits compared to traditional stack laminations, including better heat dissipation, reduced noise, and extended motor lifespan. Cleating takes motor performance to a higher level of efficiency and reliability.
Riveting involves fastening the laminations together using rivets or pins. This method provides a mechanical connection that ensures laminations remain aligned and stable. Riveting is particularly suitable for larger motor cores.
Welding involves laser and TIG+MIG welding, fusing the laminations using heat or pressure.
Gluing lamination is the application of adhesive or glue to bond individual laminations together to form the core of an electric motor. The glue is typically a specialized epoxy or resin.
Self-bonding property is through pressure and heat applied during the motor lamination stack assembly.
Thin sheets of electrical steel, known as laminations, use stamping or cut to precise shapes using specialized machinery. This high-tech manufacturing technology is becoming more and more mature.
Stacking:
The stamped and annealed laminations stack together to form the stator core.
Insulation:
The core uses insulating materials like varnish or coatings to the core to prevent short circuits between laminations and minimize eddy current losses.
Winding:
The stator winding consists of wire coils wound around the stator teeth.
Final Assembly:
The stator core assembly winding is then integrated into the motor’s housing, and other components such as rotor, bearings, and housing are assembled to complete the motor.
