Just one turn of the motor is enough to adjust the phase difference between the motor and the resolver! Introducing the revolutionary product 'Resometer' that eliminates the need for visual or manual fine-tuning.

Do you have any of these problems? ■ Adjusting with an oscilloscope takes a lot of time… ■ Borrowing items from other departments every time you adjust the resolver… ■ Wanting to quantify resolver adjustments manually… ■ Wanting to in-house maintenance of motors… ■ Spending time and effort preparing for measurements… ■ There are few people with knowledge of resolvers, and only specific individuals can make adjustments… etc. Our company-developed 'Resometer' is a measuring instrument that allows you to easily measure the phase difference between a motor and a resolver just by turning the motor by hand. The measurement accuracy is within ±0.1°, allowing for precise adjustments in a short time. Additionally, its compact size makes it easy to carry, enabling measurements even at installation sites for large motors. *For more details, please refer to the catalog or feel free to contact us.

From manual inspection to automatic inspection! A motor testing device that allows resolver adjustment without using a load device.

The "MI-1000" is a motor testing device equipped with a resolver adjustment function. In addition to testing coil resistance, thermistors, insulation resistance, and insulation breakdown voltage without a load device, it allows for position adjustment of the resolver. It also features an automatic calibration function using a reference resistor (self-check function). 【Features】 ■ Resolver adjustment possible without using a load device ■ Automatic testing of coil resistance, thermistors, insulation resistance, and insulation breakdown voltage ■ Equipped with an automatic calibration function using a reference resistor ■ Can connect to a traceability system to upload test results ■ Compatible with barcode readers and RFID readers (optional) *For more details, please refer to the PDF document or feel free to contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
