Abstract

This paper presents a newly developed sensorless electric scooter, whose traction motor (IPMSM of nonsinusoidal magnetization) is controlled by a sensorless vector control method using the “D-state-observer.” Through an actual development, this paper verifies that sensorless electric scooters can be realizable, and re-verifies that the D-state-observer has a potential applicable to other EVs. Detailed experimental results confirming the verification are also shown.
