As shown in FIG. 1, the flywheel 2 is accelerated to the braking start speed by the drive motor 1, which is a DC motor, and when the energy stored in the flywheel 2 is consumed by the brake under test 3. The torque applied to the brake 3 is measured by a torque meter 4 connected to its fixed side. Here, since the flywheel 2 is configured so that its moment of inertia can be adjusted according to the type and capacity of the brake 3 to be tested, there is a problem that the flywheel 2 generally has a large structure.

に制御される。 FIG. 3 shows an embodiment of the control device for the drive motor 1 according to the present invention.
This is a case where the desired flywheel effect is obtained by controlling the current. The armature current of the drive motor 1 is controlled by a thyristor forward converter 5, and the initial speed to be set as the brake start speed is determined by comparing the output N of the pulse pickup 6 with the setting value of the initial speed setting device 7. Using the output of the control amplifier 8 as a current command, the armature current is controlled by a current control system consisting of a current control amplifier 9, a phase controller 10, and a current detector 11, thereby performing feedback control to the initial speed setting value. The output of the speed control amplifier 8 is given to the current control system via the changeover switch 12, and the current setting value after the brake operation is given from the setting device 13 as another current command to the current control system. That is, as shown in FIG. 4, the speed control of the drive motor 1 is performed by setting the changeover switch 12 to the state shown in the figure to start the brake test, and accelerating to the set value N0 of the initial speed setting device 7 and increasing the set speed N0. 0 , and at the time t1 when the brake 3 is applied, the changeover switch 12 is switched from the state shown in the figure to perform current control based on the setting value of the current setting device 13, and the brake 3 is controlled by this current.
The deceleration characteristics are controlled to be the same as those of the flywheel.

の増幅特性を慣性設定器１６で設定する。 FIG. 5 is a configuration diagram of a control device showing another embodiment of the present invention. The difference between this figure and FIG. 3 is that the deceleration is directly set from the inertia instead of the current setting device 13, and the detected speed N of the pickup 6 is differentiated by the differentiating circuit 14 to generate the deceleration signal. This deceleration signal is passed through the inertia control amplifier 15 as a current command during brake operation, and the amplifier 15
The amplification characteristics are set by the inertia setting device 16.

なる効果がある。 Therefore, according to the present invention, in order to provide the drive motor with an initial speed adjustment function and a flywheel function,
Compared to conventional devices, the same brake test can be performed without a flywheel, and an inexpensive and compact brake tester can be constructed by simply adding a small control circuit to the drive motor control device. Furthermore, the inertia constant of the flywheel can be set by operating the motor's current or inertia setting device rather than operating the flywheel itself, making the operation simple and safe in the test room. In particular, the circuit configuration for controlling the inertial amount is simple because the current command is obtained from the differential signal of the speed detection value and the inertial amplifier that sets the amplification characteristics to obtain the current command for setting the inertial amount according to the speed. It has the effect of
