Features
Over 17 Million Units Produced Annually
Our automotive fan motors utilize our in-house ball bearings. We boast an annual production track record of over 17 million units, supplying our products to customers worldwide.
Reduced Development Lead Time via CAE Analysis
By fully utilizing analytical simulations from the early stages of development, we can identify potential issues in advance. This allows us to reduce the number of prototypes and shorten the overall design period.
Custom Designs Tailored to Customer Applications and Requests
Based on our extensive track record of custom solutions, we propose the optimal fan motor that meets your needs while fully considering your specific operating environment.
Customization Examples （Fan motor + One）
Heat Sink Unit Fan motors
We can propose not only standalone custom fan motors but also complete integrated units that include peripheral components.
Benefits of Unit Design
- Miniaturization and Weight Reduction: Optimized through total design including peripheral parts.
- Energy Savings: Helps improve the efficiency of the entire system.
- Reduced Assembly Time: Delivering as an integrated unit reduces customer assembly man-hours.
- Applications
- LiDAR, ECU cooling, Infotainment, DC-DC converters, etc.
Environmental Resistance Performance
We can also propose customized environmental resistance. In addition to high waterproof and dustproof performance, our motors can be used in harsh environments such as outside the cabin or under the hood.
Features
- IP Rating: Equivalent to IP68 and IP69K
- Operating Temperature Range: -40°C to +125°C
- Applications
- LED headlamps, LiDAR, ECU cooling, etc.
Analysis Technology
By fully utilizing CAE analysis technology to grasp the system impedance generated under actual usage environments—in addition to vibration, noise, and flow path analysis—we can develop products optimally suited for your applications more efficiently.
48V Compatible (Under Development)
With the electrification and automation of automotive systems, the power supply required for electrical components is increasing, accelerating the transition of automotive power systems to 48V. In addition to our current 5V and 12V types, we are actively developing 48V models.
Use Case Examples
Automobiles continue to evolve daily, with advancements in ADAS and autonomous driving functions, as well as improvements in comfort within the mobility space.
The amount of heat generated by electronic components, which were previously cooled by natural convection, has increased significantly, raising the demand for "active air cooling" systems using fan motors. Furthermore, as the vehicle interior continues to transform into a living and moving space, the "quietness" of fan motors is positioned as an increasingly critical priority.
Drawing from our extensive track record of adoption in a wide range of applications both inside and outside the vehicle, MinebeaMitsumi's automotive fan motors feature custom designs tailored to the optimal operating conditions. We directly address the technical challenges (needs) specific to the customer's installation locations and applications.
