04. NEW ! Torque Detector - RH series

The RH series makes torque measurement range wider beyond expectation.

-------

As the shift to electrification of various products, the development of quieter and higher quality motors has been required. The RH series can accurately detect torque fluctuations with high rigidity, and supports high-speed rotation.
It helps the development of products with outstanding quietness by minimizing cogging torque and torque ripple that cause vibration and noise.

----------

Feature

High rigidity: Highly accurate detection of torque fluctuation with high response 

The RH series is a torque detector that can accurately detect torque fluctuations with high torsional rigidity about 4.5 times compared to the existing products .

------------

Example of RH series cogging torque measurement (compared to a general torque detector)

This is an example of measuring cogging torque of the RH torque detector and a general torque detector with the CF-9400 FFT analyzer.

---------------

High speed torque measurement: Rotation speed up to 20,000 r/min

---------------------

In motors of EV scooters and compressor for air conditioners, the demand for high-speed rotation has been increasing as well.
The RH series provides high-speed rotation measurement up to 20,000 r/min and stable measurement from low (*) to high speed rotation.
(2.5 times faster than the existing models)

--------------------

Direct signal output: Ideal for installing into system

---------

RH series can be used as a stand-alone torque detector without a display unit and the direct signal output has achieved cost saving.

----------

High accuracy: Perform performance evaluation tests of motors and other equipment with high accuracy 　

The RH series torque detector has achieved highly accurate measurement with ±0.05%/FS of linearity including hysteresis (1/2 compared with the existing models).

------------------

Compact: Weight and volume are reduced to about 1/3 compared to the existing models

Smaller and lighter than the existing models and having the same center height to easily replace and handle.
