BluE Nexus’s first eAxle adopted on Toyota’s bZ4X EV


BluE Nexus Company, AISIN CORPORATION, and DENSO Company collectively developed an eAxle for Toyota’s new battery-electric bZ4X. (Earlier submit.) BluE’s first eAxle has achieved wonderful dynamic efficiency and downsizing and helps automobiles improve their electrical mileage. BluE was established in April 2019 to develop and promote electrical techniques and driving modules by combining the strengths of AISIN, DENSO and Toyota in electrification (earlier submit).

The eAxle is an electrical driving module that integrates a motor, an inverter, and a transaxle. BluE, AISIN, and DENSO have collectively developed three new fashions: a 150kW specification (entrance) for FWD automobiles and 80kW specs (entrance and rear) for 4WD automobiles.


This product has achieved wonderful dynamic efficiency and excessive torque by growing output density. Optimizing cooling contained in the eAxle using simulations and applied sciences nurtured thus far, adapting warmth administration expertise and enhancing the double-sided cooling expertise for inverter layers assist to extend output density.

Moreover, top-class electrical mileage has additionally been achieved via the optimum magnetic design of the motor, the becoming a member of expertise to shorten coil ends, low-viscosity oil for the eAxle, and loss discount applied sciences reminiscent of the brand new reverse-conducting IGBT (RC-IGBT).

The e-Axle has been considerably downsized through applied sciences together with a built-in construction that comes with an inverter into the transaxle, a downsized motor, and a shortened distance between the shafts achieved by adopting an output shaft. The eAxle to be mounted within the entrance of a automobile has a lowered longitudinal size, and the one to be mounted within the rear of a automobile has a lowered top, serving to develop the passenger and baggage compartment areas.

AISIN has developed and produced greater than 5 million electrical models because the launch of its first hybrid transmission in 2004. In the meantime, DENSO has developed and produced greater than 20 million inverters because the launch of the primary Prius in 1997.

Along with the experience of the AISIN and DENSO, the three corporations have developed BluE’s first eAxle by using BluE’s know-how relating to the optimization and modularization of parts, and the corporate’s functionality to adapt to quite a lot of automobiles.
