摘要：A method and apparatus for determining a fault in an electric motor (50)determines a calculated star voltage (Vstar-calc) of the electric motor. The calculatedstar voltage (Vstar-calc) is compared to a measured star voltage (Vstar-meas) of theelectric motor (50) to determine a star voltage error (Vstar-err). The fault in the electricmotor (50) is determined when the star voltage error (Vstar-err) exceeds apredetermined maximum star voltage error (Vstar-err-max).
