飯島精機 List of Products and Services

This is a motor core assembly product. The material of the laminated core is 35A440, which is primarily used for power transmission devices and is classified as a laminated core product. This motor core undergoes processing by wire cutting after the electromagnetic steel sheets are laminated and bonded in advance. Our laminated core's lamination bonding technology enables high-precision lamination bonding filled with unique know-how, and it is one of the technologies that has received much appreciation from our customers. Additionally, in the wire cutting process, the T-shaped stator part is processed to be divided into “-” and “I” shapes. After that, a bobbin is attached to the laminated iron core in the “I” shape, and copper flat wire is wound around it. We accommodate the procurement of various 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 motor cores and resolvers to mass production. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices. If you are facing issues with the design and manufacturing of custom motor cores or precision press parts, please feel free to contact our custom shim manufacturing center.

This is a resolver (rotary angle sensor). The material is 35A440, and it is a product mainly used for power transmission devices, classified as a laminated core product. This resolver undergoes processing by wire cutting after the electromagnetic steel sheets have been laminated and bonded in advance. Our laminated core's lamination bonding technology enables high-precision lamination bonding filled with unique know-how, and it is one of the technologies highly regarded by our customers. Additionally, this resolver required high precision. Therefore, we achieved high-precision wire cutting processing by dividing the cutting of each processing area into four stages. We accommodate the procurement of various 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 resolvers. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices. If you have any concerns regarding the design and manufacturing of custom motor cores, resolvers, or precision pressed parts, please feel free to contact our custom shim manufacturing center.

• DC Motor

This is a mass-produced stator core. The material is 50A300, and it is used in power transmission devices. If you take a closer look at the overhead photo, you can see that it is laminated by performing round rivets in two places. In our company, for this type of riveting, we manufacture the stator core through lamination within the mold. We have received requests from customers to ensure the strength of the rivets and the vertical accuracy of the products as precisely as possible. Our company manufactures press parts centered around laminated cores to meet customer requirements, including riveting strength and vertical accuracy. We are 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 of custom motor cores and resolvers to mass production. Additionally, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices. If you have any concerns regarding the design and manufacturing of custom motor cores or precision press parts, please feel free to contact our custom shim manufacturing center.

• DC Motor

This is a T-shaped 6-piece laminated motor core (Poki-Poki core). The material is 35A440, and it is primarily used for power transmission devices. Precision of perpendicularity and parallelism is required to be within 0.05mm, necessitating advanced precision mold manufacturing technology, which is why we were consulted by the company that specializes in burr-free precision pressing. Additionally, while other companies also manufacture individual T-shaped laminated cores, this one is laminated in a state where six T-shaped cores are connected together. If you are in need of custom motor core design and manufacturing or precision pressed parts, please feel free to download the materials or contact our custom shim manufacturing center.

• DC Motor

This is a laminated motor core (φ110×35×0.2mm). The material is 50A300, and it is primarily used for power transmission devices. This laminated motor core is assembled using a progressive die that performs lamination within the mold. A precision of 0.05mm is required for perpendicularity, parallelism, coaxiality, and roundness, necessitating advanced precision mold manufacturing technology, which is why we were consulted by the company that specializes in burr-free precision pressing. We are 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 solutions from prototype processing of custom motor cores and resolvers to mass production. Additionally, based on the data accumulated in our unique production management system, we offer products to our customers at reasonable prices. If you are facing issues with the design and manufacturing of custom motor cores or precision pressed parts, please feel free to contact our custom shim manufacturing center.
