[Production Example] Motor Core (φ110×0.2mm)

Motor core by wire cutting

This is a motor core (φ110×0.2mm). The material is 35A440, and it is primarily used as a component for power transmission devices. For this core, we processed it by sandwiching multiple stacked blank materials with thicker iron to reduce vibration during processing caused by the injection of cutting fluid. The processing steps were carried out in the order of "outer circumference rough machining → hole rough machining → outer circumference finishing → hole finishing." Additionally, for motor cores of this shape, having only one start hole on the outer circumference would cause the workpiece to move during processing, so we created two or more start holes for machining. Our company is capable of sourcing a wide range of materials, from general iron and SUS to amorphous products and special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices. Therefore, we also propose cost reduction from the design stage based on past processing data. If you are facing challenges with the design and manufacturing of custom motor cores or precision press parts, please feel free to contact our custom shim manufacturing center.

[Production Example] Stator Core (φ300×0.25mm)

Motor core made by press processing.

This is a stator core (φ300×0.25mm). The material is 25A, and it is a product used for power transmission devices. This stator core is quite large, with a size of φ3000mm, and using wire cutting would incur enormous costs in terms of both time and money. Therefore, our company manufactured it by creating a prototype mold and performing punching through press processing. While the size is large, the precision is similar to that of other parts, making it a product that requires high processing and assembly precision of the press mold components. However, at our custom shim manufacturing center, we were able to produce it with a beautiful finish and almost no burrs through burr-free precision press processing using molds with good assembly precision. Our company is capable of sourcing a variety of materials, not limited to general iron and SUS, but also including amorphous products and special alloys, providing one-stop solutions from prototype processing to mass production of custom motor cores and stator cores. Additionally, based on our unique data, we offer products to customers at reasonable prices. If you are having trouble with the design and manufacturing of custom motor cores and stator cores, please feel free to contact our custom shim manufacturing center.

[Production Example] Irregularly Shaped Hole Motor Core (φ110×0.2mm)

Motor core made by press processing

This is a non-standard shaped hole motor core (φ110×0.2mm). The material is 20A, and it is primarily used as a vehicle component. This core is processed using our specialty burr-free precision pressing technique with a total knockout mold, significantly reducing burrs. Additionally, the flatness is finished beautifully, making it a precision pressed product. Furthermore, this core features non-standard hole processing, with hole punches arranged according to the shape of the magnet requested by the customer. Our company is capable of sourcing a variety of materials, not only standard iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing to mass production of custom motor cores and resolvers. Based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices. If you are facing challenges with the design and manufacturing of custom motor cores or resolvers, please feel free to contact our custom shim manufacturing center.

[Production Example] Stator Core (φ250×0.2mm)

Motor core made by press processing

This is a stator core (φ250×0.2mm). The material is 20A1500, and it is a product used for vehicles. This stator core is relatively large at φ250mm, and if processed by wire cutting, it would incur enormous costs in terms of both time and money. Therefore, our company manufactured it by creating a prototype mold and performing punching through press processing. Due to the narrowness and high number of teeth, high precision in the processing and assembly of the press mold components is required. However, at our custom shim manufacturing center, we were able to produce a clean finish with almost no burrs using precision press processing with molds that have good assembly accuracy. Our company is capable of sourcing a variety of materials, not only common iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing to mass production of custom motor cores and stator cores. Additionally, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices.

[Production Example] Prototype Cut Product of Motor Core (Made of SECC)

Motor core by wire cutting

This is a motor core for vehicles. The material is SECC, and it has been processed using wire cutting. This motor core is a prototype cut piece for confirming the shape. Normally, motor cores are processed using electromagnetic steel sheets such as 20A1500, but this time, there was a request from the customer to quickly touch and verify the shape. Therefore, we have manufactured it using wire cutting with SECC material to ensure a short delivery time. Our company is capable of sourcing a variety of materials, not only standard iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing to mass production of custom motor cores. Additionally, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices. As a result, we also propose cost reduction from the design stage based on past processing data. If you are having trouble with the design and manufacturing of custom motor cores, please feel free to contact our custom shim manufacturing center.
