In this paper a reduction method for torque–ripple is evaluated. Synchronous reluctance motors (SynRM) combine highly efficient operation with low initial costs of the drive system. The disadvantage of the used salient pole rotor structure is that a strong torque–ripple could occur. To deal with this unwanted torque harmonics the classical mathematical model of the SynRM has to be enhanced. With this extended model a torque–ripple suppression method was developed which does not require detailed information of the system. These theoretical approaches were experimentally tested on a prototype to verify the performance of the enhanced drive system.
