In a motor driving device, a current detector detects a value of the motor current, and a limit variable calculator calculates a calculation value of a limit variable for limiting the command current. A determiner determines, based on a relationship between the value of the motor current and the calculation value of the limit variable, whether the motor current is in a less-response situation to change of the command current. A current limiter determines whether to limit a value of the command current based on the calculation value of the limit variable in accordance with a result of the determination of whether the motor current is in the less-response situation to change of the command current.
