Abstract

The dual three-phase machines are proposed for applications requiring continuous operating even under a partial fault. The two windings are supplied by two separate inverters. Thus, in the event of a fault of one winding, this can be disconnected and the machine continues to operate with the healthy winding. This paper investigates the thermal behaviour of a machine with dual three-phase winding during faulty operating conditions. Analytical and finite element analyses are carried out in order to analyze the machine behaviour during the fault. In addition, experimental tests on an fractional-slot interior permanent magnet prototype are included.
