    • Pre-load function to avoid excessively high rotation speeds

    (∗1) Select “WT1800E” in the “WT Compatible Command Type Setting” of WT5000. Up to six elements can be used.

    Accurate measurements without inertial effects

    In the point measurement mode based on our own control method, the time taken for the motor speed to stabilize (the “wait time”) can be set to eliminate the effect of the moment of inertia on the load torque value and rotation speed. And in the sequence measurement mode used for dynamic measurements, it is possible to minimize the effect of inertia on measurements by using correction values obtained through simple operations.

    Torque control without PID parameter setting

    Setting up the conventional dynamometers involves adjusting a different set of P, I and D values for each motor being measured, which requires a knowledgeable and experienced operator. In Sugawara’s unique torque control method, there is no need for PID parameter setting. To obtain unambiguous data, all you have to do is fix the motor and shaft correctly and set up the points where torque or rotation speed measurements are to be made. The results will be the same no matter who performs the measurements.

    Four advanced measurement modes

    Four measurement modes can be selected to suit each application.

    • High accuracy point mode with simple settings

    You can easily measure the S-T (rotational speed-torque) characteristics simply by setting the measurement points. Torque control, rotational speed control and brake control can be combined in one measurement. The data is not affected by moment of inertia because it measures the value at a stable operating point.

    • Sequence mode with support for various types of measurement

    By controlling the torque, rotation speed and braking over time, it is possible to perform various tests such as sweep measurements, endurance tests and cycle tests. This makes it possible to perform load simulations based on actual use conditions, and durability tests that combine test conditions and idling conditions and repeat it up to 10,000 cycles.

    • Inspection mode specialized for pass/fail testing

    Pass/fail testing can be performed by setting up to five upper and lower limits for measurement items based on torque, rotation speed or braking. By specifying a file name in advance, you can automatically generate a file listing the time, sequence number and results of each measurement.

    • Manual mode where measured values are displayed in real time

    In this mode, you can set and control the torque, rotation speed or braking at a single point, and display all the corresponding measured values in real time. This mode can be used for simple behavior observations and for the measurement of starting torque.

    Additional I/O options for versatile functionality

    The addition of extra I/O options provides you with various extended functions.

    • Simultaneous measurement of voltage signal input from external sensor
      Using an analog 4ch input (0–10 V), it is possible to simultaneously measure and store voltage inputs from external sensors such as temperature and flow rate sensors. The scaling and unit of these inputs are user configurable. These input signals can be plotted simultaneously on a graph of torque measurements, and can also be configured as pass/fail judgment criteria.
    • Control an external motor power supply
      This function allows you to switch a motor’s power supply on and off (via contact inputs). Also, if you use a power supply that has an analog input, the analog voltage output function allows you to change the power supply voltage during the measurement sequence.

    User-friendly graphical user interface

    The graph displays 5 axes × 3 items in real time. We have improved the operability of this display by adding a graph axis auto setting function. You can also customize the graph line style and dot appearance.

    It is also easy to change the power analyzer settings in software.

    LabVIEW software that can easily be customized

    The dedicated TORQuick software is written in LabVIEW and can be flexibly adapted to diverse requirements. Please contact our sales department for further details.

    HB series dynamometers

    We have improved the torque measurement accuracy of the hysteresis brake to ±0.1%. A total of 13 models are available, with rated torques ranging from 5 mN·m to 50 N·m. The three models with maximum torques of 50 mN·m, 100 mN·m and 200 mN·m can attain a world-class no-load rotation speed of 60,000 rpm due to our high-precision processing.
