Implementing JMAG


JMAG's Role in Supporting the Electrification of Compact Vehicles

Suzuki's newest Solio model is equipped with a mild hybrid system. For compact vehicle electrification, simply adding electric components cannot improve fuel consumption sufficiently. To elicit maximum performance without wasting magnetic circuits, JMAG is used to carefully identify magnetic flux flow occurring in the rotor of a permanent magnet synchronous motor (PMSM). We spoke with Dr. Aoyama, Mr. Akaki, and Mr. Deng from the Electric Component Development Department regarding means to reduce costs and motor weight, as well as the difficulty in compact vehicle electrification.
