	This newly developed Meidensha e-Axle is used in the drive motors of Nissan's Note, Aura e-4WD rear, and Sakura EVs. The e-Axle for e-4WD rear and Kei-class (mini-vehicle) EVs is compact and consists of an inverter with direct-cooled IGBTs, an IPMSM-type motor with SC windings, and a speed reducer. Although the housing shape and other features have been adapted to the mounting requirements of the Aura e-4WD rear, the basic parts such as the motor's active parts (electromagnetic circuit) are believed to be the same as those of same model (MM48) of both the e-4WD rear and Kei-class EV drive motor.<ref>https://www.marklines.com/en/report/rep2381_202210</ref>		This newly developed Meidensha e-Axle is used in the drive motors of Nissan's Note, Aura e-4WD rear, and Sakura EVs.
