Permanent magnet synchronous machines having tooth-coil windings with an alternation of wound and non-wound teeth appear to be among the best suited can didates for building high performance and high reliability electrical drives. After a short presentation of the main features of these machines, this paper discusses a modular control architecture which allows to make their operation fault-tolerant to the loss of feeding of one phase in order to increase their reliability. The main feature of the proposed architecture consists in using, for ensuring the torque control, one Park reference frame per phase. It is shown that this control architecture allows an easy detection of the faulted phase when a fault occurs and a simple control reconfiguration in order to palliate the failure.
