Investigation of EV Motor Disassembly

Investigation of EV Motor Disassembly

Daito Analysis Research provides support for your motor development and material proposals using the material analysis technology and magnetic material evaluation technology that we have cultivated over many years.

As the electrification of vehicles accelerates, the development of high-efficiency motors has become an essential element for achieving carbon neutrality, requiring improvements in both efficiency and reliability. Enhancements in the performance of magnets and core materials, as well as structures and materials with high environmental resistance, are desired. Our company will provide support and material proposals based on our long-established expertise in structural material analysis and magnetic material evaluation.

Daito Analysis Research provides support for your motor development and material proposals using the material analysis technology and magnetic material evaluation technology cultivated over many years.

As the electrification of vehicles accelerates, the development of high-efficiency motors has become an essential element for achieving carbon neutrality, requiring improvements in both efficiency and reliability. Additionally, in response to the rapidly changing social conditions, reverse engineering (disassembly investigation) is an indispensable factor for shortening development periods and controlling costs. Our company will provide support and material proposals using the material analysis and evaluation technologies we have cultivated over many years.

Investigation of metal parts damage incidents

Investigation of metal parts damage incidents

It is possible to investigate the cause of metal parts damage accidents.

When metallic materials fail, the mode of failure changes due to various factors such as the properties of the material, applied stress, and environmental conditions. By observing the fracture surface in detail using an electron microscope, it is possible to identify the cause of the failure to some extent from the fracture morphology. Failure modes can be broadly classified into four categories: ductile fracture, brittle fracture, fatigue fracture, and environmental fracture. Ductile fracture involves significant deformation, such as elongation, before failure occurs. Brittle fracture is characterized by crack propagation at a high speed without plastic deformation. Fatigue fracture occurs when cracks gradually propagate due to repeated stress. Environmental fracture is a failure that is significantly accelerated by corrosive environments, leading to rapid crack propagation.

Investigation of soft magnetic materials for EV motors

Investigation of soft magnetic materials for EV motors

We will conduct benchmark research and development support for soft magnetic materials for motors, such as electrical steel sheets and powder magnetic cores.

By utilizing our material analysis technology, we can perform the following analyses on soft magnetic materials used in EV motors: 【Magnetic Measurement】 We conduct measurements of DC magnetic properties and AC magnetic measurements. Analysis of materials taken from existing motors is also possible. 【Steel Sheet Grade Investigation】 For electrical steel sheets, we can estimate JIS equivalent grades by comprehensively considering the results of material property investigations (such as hardness), component analysis, and magnetic measurements. 【Coating Investigation】 Using devices such as scanning electron microscopes (SEM), we can investigate the insulating coatings applied to steel sheets and powders. 【Development Support】 Many electrical steel sheet materials have a correlation between crystal orientation and magnetic properties, which can be quantitatively evaluated. By understanding the magnetic properties based on the orientation of the steel sheets, we contribute to motor design and improvements in manufacturing processes. Additionally, the magnetic properties deteriorate due to the strain induced by powder compression molding or steel sheet punching, but this strain can be quantitatively evaluated. This can be utilized for optimizing processing and strain removal processes.
