Torque detector
MTシリーズ（TS-8700用）

High-performance motors, including ultra-precision motors, are used in many everyday items, such as automobiles, home appliances, industrial equipment, and office/audio equipment.
Furthermore, there are many types of motors available to suit various applications, ranging from ultra-high-speed to low-speed, and even ultrasonic types.

To meet the needs of measuring the characteristics of these diverse motors, Ono Sokki offers a wide range of MT series detectors, including those for high-speed rotating motors, high-capacity motors, torque ripple measurement, cogging torque measurement, and more.

Furthermore, we have added a new lineup featuring the compact, high-rigidity torque detector RH series (10 N･m / 20 N･m).
The RH-type torque detector is a torque detector that achieves high accuracy (±0.05 % FS) and high rigidity (4.5 times that of conventional models), enabling measurement of motor torque fluctuations up to higher frequency ranges.
*In addition to the MT series detector, the TS-8700 Torque Station Pro is required for motor characteristic measurement.

MT-82 M/T/R Torque Ripple/Cogging Torque Detector

MT-82 M/T/R Torque Ripple/Cogging Torque Detector

This detector is suitable for measuring torque ripple when the motor is excited and cogging torque when the motor is de-excited.

The MT-82M** allows for constant control measurement between 0.5 and 5 r/min, while some MT-82T** models allow for constant control measurement between 2 and 15 r/min.

Measurement Items Torque, rotational speed, rotational angle*, current*, voltage* (*: optional)

/E1 Encoder

With the exception of some torque ripple and cogging torque detectors, rotation angle measurement and angle sampling can be performed in 0.1° increments.

* Manual (N) - For time-series measurements such as continuous, angle measurement is possible within the specified rotational speed range of the MT detector. However, for angle measurement (angle sampling) only, the rotational speed range is limited to the lower limit of the MT detector to 5 r/min. Also, if there is resonance within the rotational speed range, angle measurement (angle sampling) may not be possible, and you will need to change the rotational speed to perform the measurement.
