Small High-Rigidity Torque Detector RH Series
Expand 'hakaru' to measure the torque of various products.
In the automotive industry, electrification is rapidly advancing, and many types of motors are being used, leading to a demand for motors that minimize cogging torque and torque ripple, which can cause vibrations and noise. Therefore, there is a need for a highly rigid torque detector that can accurately capture torque fluctuations. On the other hand, there is an increasing demand for high-speed rotation specifications for motors used in EV scooters and compressors for air conditioners overseas. We have developed a torque detector that can meet these demands.
