空スペース Product Lineup

Flywheel energy storage systems mostly used magnetic bearings. As a result, scaling up was difficult, and the associated equipment, including cooling systems and touchdown bearings for emergency stops, was very expensive, making it unable to compete with secondary batteries. The proposed flywheel energy storage system achieves overwhelming low costs by using our ADB (Autonomous Distributed Rolling Bearings) as low-cost, highly durable bearings in a vacuum. Additionally, by separating the motor for power generation/storage into a rotor inside the vacuum chamber and a stator outside, self-discharge is nearly zero, and the quantity can be adjusted according to demand, allowing for arbitrary changes in power and energy. Furthermore, the chamber that supports the bearings with a core pillar significantly reduces size and weight.

• Prototype Services

【Urgent Recruitment】 Manufacturers of ADB (equivalent to Minebea Mitsumi A-2520) for EV battery manufacturing lines. We will provide the necessary patent licenses. So far, we have completed the first prototype through outsourcing and the second prototype with Minebea Mitsumi, receiving high praise from our client (a major EV battery manufacturer in Japan). However, it is expected that the equipment currently being maintained by the client is not licensed by us, leading to anticipated special demand for disposal and replacement of the equipment. The required number of bearings is estimated to be over 50,000 units.

• Metal bearings

The "ADB Angular Ball Bearing" is a bearing that minimizes friction to the greatest extent possible. By introducing it as a component, it enables bearing replacement, maintenance, and reduction of equipment power consumption. If you adopt the technology to manufacture bearings, fuel efficiency can increase by 7.5%, providing a competitive edge with a differentiation factor of DmN7.5 million. 【Features】 ■ Reduces equipment management costs ■ Clear technical PR for products ■ Quickly resolves faulty bearings ■ Business that develops countermeasures ■ A weapon for product differentiation (7.5% fuel efficiency increase / DmN7.5 million) *For more details, please refer to the PDF document or feel free to contact us.
