    In recent years, the rapid advancement of electrification has led to increasingly sophisticated performance demands for motors.
    These motors are expected to deliver high efficiency while minimizing noise and vibration.
    In the development of such motors, in addition to evaluating basic characteristics, it is essential to measure factors such as efficiency, cogging torque, and torque ripple, which can cause noise and vibration.
    Our motor testing systems contribute to the development of high-performance motors by accurately capturing motor behavior for precise evaluation.

  • Sales point (English)

    Using Ono Sokki’s proprietary phase difference method, we have achieved high-precision and highly reproducible torque measurement across a wide rotational speed range—from low to high speeds.
    Building on this technology, we offer systems capable of comprehensive measurement and evaluation of various performance characteristics, including the torque characteristics of small AC/DC motors.
    Our products also feature enhanced torsional rigidity, enabling precise detection of subtle torque fluctuations.
    They support the measurement of critical parameters such as "torque ripple" and "cogging torque," which are essential for improving motor efficiency and reducing noise, thereby providing strong support for motor development.
    Furthermore, we offer motor testing systems for evaluating basic characteristics in a wide range of applications, including motors for HEV/EV, electric power steering (EPS), compressors, robotics, and household appliances such as vacuum cleaners and washing machines.
