Abstract
A PMSM stator inter turn short fault generates a back emf and an impedance unbalance. Those unbalance causes a torque ripple and an escalating partial heat defect. This paper proposes a fault detection scheme based on the PMSM dynamic model under the inter turn short which is derived in the positive and the negative sequence synchronous reference frames. To validate the proposed scheme, the finite elements method (FEM) with electric circuit is conducted on the PMSM.
