タ。[Scope of Claim for Utility Model Registration] Detecting the driving power and rotational speed of the motor, and based on these detected values, obtaining a current command indicating the armature current value of the motor by an armature current calculation section,
By outputting this current command to the motor drive unit, the detected value of the motor rotation speed is compared with a threshold value in a brake dynamometer that generates an inertial load when the test brake is operated, and the detected value is A comparator unit that outputs a control switching command when the voltage falls below a threshold, and an armature current memory that latches the motor armature current value upon receiving a control switching command and outputs this armature current value as a current command. A part that selectively outputs current commands from the armature current calculation part and the armature current storage part to the motor drive part, and switches to the armature current storage part side by receiving a control switching command. A brake dynamometer characterized by comprising a current command switching section.
