Astemo Presents a More Compact and Powerful Electric Motor
The company Astemo, an alliance between Honda and Hitachi, has unveiled a new electric motor designed to transform how electric vehicles are built. Its main goal is to make propulsion assemblies lighter and take up less space, freeing up area for batteries or the cabin. This advancement is achieved by optimizing the magnetic flux, generating more power without needing more material. 🚗⚡
A Design that Integrates and Simplifies
The innovative architecture of this motor consists of integrating the inverter directly into its own housing. This approach eliminates high-voltage cables and connectors that normally connect both units. The result is a smaller package that also reduces energy losses in the connections. To handle heat effectively, the cooling system has been completely redesigned, allowing the motor to operate at high performance sustainably.
Key Advantages of the Integrated Design:- Eliminating cables and connectors between the motor and inverter saves space and weight.
- Redesigning cooling manages heat more effectively, maintaining performance.
- Simplifying the assembly line can reduce costs when produced on a large scale.
By using less electricity to produce the same force, the motor increases the vehicle's usable range.
Technology for Greater Range and Versatility
Improved efficiency is at the core of this development. Engineers have used magnets with a special arrangement and more precise current control in the coils. This allows the motor to consume less energy to deliver the same torque and power, translating directly into more kilometers per charge. The unit is compatible with various drivetrain configurations, whether front-wheel, rear-wheel, or all-wheel drive (4x4).
Features that Boost Efficiency:- Using magnets with a special arrangement optimizes the magnetic field.
- Precisely controlling the current in the coils reduces energy consumption.
- Being compatible with multiple traction configurations makes it versatile for manufacturers.
The Future of Electric Propulsion
Astemo plans to make this new propulsion unit available to automobile manufacturers starting in 2027. This advancement highlights the industry trend of creating electric motors that are both more powerful and smaller. The evolution suggests that power density will continue to increase, making electrification even more practical and attractive for all types
