【Pick up】Thermal Management
As automobiles electrify, sintered parts are increasingly being incorporated into cooling mechanisms. Sintered parts contribute to the efficiency of thermal management systems owing to their advantages (porous, ferromagnetic, near net shape, etc.)

Examples of our technology applications
Axial Electric Pump (Electric Oil Pump using Axial Flux Motor)
The need for high efficiency of thermal management systems is increasing along with the electrification of automobiles.
In response to this, we have developed an axial electric pump that combines our technology, Axial Flux Motors, with an internal gear oil pump, to realize high efficiency, compactness and light weight of electric oil pumps.
We adopted a design that places the oil pump in the central space, which is a structural feature of the Axial Flux Motor, which made it possible to manufacture small, thin oil pumps.
Our development capabilities of motor and oil pumps allow us to propose electric oil pumps tailored to customers’ needs and provide evaluation support.
Proposed applications : Lubrication /Cooling /Hydraulic oil pumps
Axial Electric Pump
Adopted a design that places the oil pump inside the motor core
① 40% thinner than a radial motor pump.
② The motor has a self-cooling function.
