| Abstract |
Aerospace as well as automotive applications demand auxiliary drives with a high power density and
a high reliability. Permanent magnet synchronous motor drives (PMSM) offer a high power density.
Reliability can be improved by special motor designs [2], [5] or by means of remedial operation
strategies [6], [1]. This paper describes a remedial approach with a standard three phase machine. If
one phase is faulted, the remaining phases won’t be affected and will achieve in most cases the same
performance as the unfaulted drive. This will be reached by separating the three phases electrically.
Some applications demand high torque at low speed with little or no torque ripple. Special attention
will be paid to the torque ripple, if a part of the drive is faulted. |
