injecting negative d-axis current to oppose magnet flux so a permanent magnet motor can run above base speed within the inverter voltage limit.

In electric machines, flux weakening refers to injecting negative d-axis current to oppose magnet flux so a permanent magnet motor can run above base speed within the inverter voltage limit. This meaning comes from Morimoto (1990) in IEEE Transactions on Industry Applications.[1]
