title = "An improvement to standard polyphase induction machine efficiency tests utilizing direct online stator winding resistance measurement",
abstract = "A direct online stator winding resistance measurement scheme is proposed as a means to improve standard efficiency tests of polyphase induction machines. To enable resistance measurement a DC current is injected online into the stator winding and response voltages are captured. In experimental tests an unequal number of anti-parallel diodes has been used to inject DC current. A bespoke temperature controlled shunt has been used to improve accuracy of DC current measurement. Experimental results from a standard efficiency test conducted to IEC 60034-2-2007 on a 15 kW 3 phase induction motor are presented.",
