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 autos enhance their electrical mileage. BluE was established in April 2019 to develop and promote electrical programs 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 autos and 80kW specs (entrance and rear) for 4WD autos.

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 to date, adapting warmth administration know-how and bettering the double-sided cooling know-how for inverter layers assist to extend output density.

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

The e-Axle has been considerably downsized by way of 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 car has a decreased longitudinal size, and the one to be mounted within the rear of a car has a decreased 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 elements, and the corporate’s functionality to adapt to quite a lot of autos.
