Recently, most fault tolerant controls have been applied in permanent magnet synchronous motors (PMSM) and permanent magnet assisted synchronous reluctance motors (PMa-SynRM), however, previous fault tolerant controls are hard to apply into synchronous reluctance motor (SynRM). This is because that torque ripple under these fault tolerant controls is unacceptable. Hence, this paper presents a new fault tolerant control for a five-phase SynRM to reduce torque ripple under single phase fault. Process of calculating third harmonic current is the critical point of this proposed method, which is obtained by neglecting changes of inductance because of small magnitude of third harmonic current. The further Finite Element Analysis (FEA) and experimental results validate the availability of proposed method.
