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 4):
The motor drive device according to  claim 1 ,\n wherein the storage is configured to store each resistance value of the plurality of resistances of the dynamic brake circuit, and wherein the failure determiner is configured to determine, based on a difference between the initial current value and an ideal current value calculated from the resistance value, whether the initial current value is abnormal.
