Reading from other comments: the 95% efficiency in "traditional" motors is only reached in ideal, fixed conditions (in terms of speed and torque). New advanced control systems increase efficiency at different speeds/torque.

Accurate! For many applications it was considered irrelevant and motors were just wound for a fixed speed. Outside this range the efficiency can drop drastically, below 50% for some motors (hence why shunt-wound motors were once used).
