Abstract:
A motor drive device includes an inverter configured to convert a DC voltage to an AC voltage by switching power devices, a current detector configured to detect a current output from the inverter, a current controller configured to generate a voltage command, a control signal generator configured to control switching of the power devices, a dynamic brake circuit provided with relays and configured to short-circuit an output side terminal of the inverter via resistances, a storage configured to store an initial current value and a first threshold value, and a failure determiner configured to compare a current value and an initial current value after a predetermined time has elapsed since detection of the initial current value, and determine presence or absence of a failure based on a result of comparing a change rate of the current value from the initial current value with the first threshold value.

Claim (Index 3):
The motor drive device according to  claim 1 ,\n wherein the storage is configured to store a time, when the current detector detected the current value, and the current value, and wherein the failure determiner is configured to predict a timing of the failure based on a degree of temporal change of the current value.
