Torque detector
MTシリーズ（TS-8700用）
High-performance motors, including ultra-precision motors, are used in many everyday items, from automobiles and home appliances to industrial equipment and office/audio equipment. Furthermore, there are many types of motors available, ranging from ultra-high-speed to low-speed and even ultrasonic types, each suited to a specific application.
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 lineup equipped with the compact, high-rigidity RH series torque detector (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
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.
MT-84 M/T/R Hysteresis Brake Type Detector
Supports high rotational speeds
When used in combination with the TS-8700, it automatically measures the rotational speed and torque characteristics of the motor.
It offers torque control and rotational speed control, and supports both AC and DC motor measurement.
MT-85 M/T/R Powder Brake Type Detector
For measuring relatively large capacity, low rotational speed motors such as geared motors.
When combined with the TS-8700, it can automatically measure the rotational speed and torque characteristics of a motor.

Examples of applications for torque detectors and torque stations
Microtech Laboratory Co., Ltd.
In direct-drive motors that output high torque from low rotation speeds, reducing the cogging torque, which is a bottleneck, enables highly precise operation.
