Custom Bolting Motor Stator Lamination Stacks

The application area for bolting stator cores encompasses a broad range of industries. Primarily, it is used in the manufacturing of electric motors and generators, where precision, durability, and reliability are paramount.

Automotive, aerospace, and renewable energy sectors heavily rely on this technology. Bolting stator cores are also used in power generation, industrial machinery, and various consumer electronics. The versatility of this application extends to any sector requiring efficient and sturdy electrical motor systems.

Capabilities Of Stator Stacks Bolting

The stator bolting process is a critical step in assembling the stator of an electric motor or generator. It involves securely fastening the stator laminations together using bolts. This process is essential to ensure the structural integrity and performance of the stator core.

The stator is made up of a series of thin metal sheets called laminations. These laminations stack and align to form the stator core. To join these laminations together, holes are drilled through the laminations, and bolt threads are inserted. The bolts are then tightened to compress the laminations together, creating a solid and rigid structure.

The stator bolting process requires precision and attention to detail to ensure that all the laminations are axial alignment correctly and that the external bolt threads are tightened to the appropriate torque. Additionally, no special tooling or lifting of the frame is required, making the replacement process easy and cost-efficient.

Advantages Of Stator Core Bolting

Structural Integrity

Bolting the stator core ensures that individual laminations are securely fastened, preventing any movement or distortion during operation. This enhances the overall structural integrity of the motor or generator.

Core Loss Reduction

A properly assembled stator core minimizes core losses, leading to improved efficiency and performance of the motor or generator. This results in lower energy consumption and higher output.

Ease of Maintenance

The bolted stator core can be easily disassembled for maintenance or repair purposes, enabling quick and efficient servicing of the motor or generator. This reduces downtime and associated costs.


The bolting process can be tailored to meet specific requirements, making it suitable for a wide range of motor and generator applications across various industries. Optimization of performance and efficiency.


The stator core bolting process is scalable, allowing for the assembly of stator cores of varying sizes and configurations. This makes it suitable for both large-scale industrial applications and large stators.
