[Production Example] Stepper Motor Core

[Production Example] Stepper Motor Core

Core using press-type inner layer.

This is a laminated core for stepping motors. It was manufactured by laminating electromagnetic steel sheets with a thickness of 0.2t using round dowel rivets. Unlike the common thicknesses of 0.35t or 0.5t for laminated core steel sheets, the 0.2t round dowel rivet lamination requires a very high precision press mold. However, our company designs and manufactures the press molds for laminated core production in-house, and we have numerous achievements and know-how regarding the prototype processing of laminated cores, so we can handle the production of laminated cores with such high precision without any issues. We are capable of sourcing a variety of materials, not only general iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Additionally, 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 having trouble with the design and manufacturing of custom shims, please feel free to contact our custom shim manufacturing center.

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

[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)

[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.

Magnetic sensor (core and shield) permalloy

Magnetic sensor (core and shield) permalloy

A core to capture weak magnetic signals strongly, and a shield to direct the magnetic influence away.

●Current Sensor Current clamp cores (clamp meters) measure by clamping around power lines, and some high-sensitivity models use permalloy. Additionally, gap cores, which have a portion of round or square iron cores cut out, detect magnetic fields by inserting Hall elements into the cut section. Permalloy, which can detect even slight magnetic fields, plays an important role in controlling the batteries of hybrid and electric vehicles. ●CT (Current Transformer) Core Current transformers are devices that adjust current values, effectively reducing large currents on the primary side to manageable levels on the secondary side. One example is the ZCT (Zero Sequence Current Transformer) used in leakage breakers in distribution panels, where the highly sensitive permalloy reliably detects even minor electrical leaks. ●EI Core This is a core shaped literally like an "E" or "I." Permalloy cores have a higher permeability compared to other magnetic materials and are used in small power transformers and current transformers. *For inquiries or consultations regarding our products, please use the contact form on our website. 【Contact Us】https://www.ohtama.co.jp/contact.html
