A Strain Gauge Torque Transducer Calibration Study

-This paper presents for the study of torque transducer (torque sensor) calibration built into a rotating shaft, in this case uses strain gauge, which was done with, and the output signal of the "voltage (mV/V)" has been taken for each weight, increasing and decreasing the weights. The data have been taken three times which they have been divided into three series. First and foremost, the avera...

Towards Scalable Strain Gauge-Based Joint Torque Sensors

During recent decades, strain gauge-based joint torque sensors have been commonly used to provide high-fidelity torque measurements in robotics. Although measurement of joint torque/force is often required in engineering research and development, the gluing and wiring of strain gauges used as torque sensors pose difficulties during integration within the restricted space available in small join...

Cogging Torque Control in Brushless Dc Motors

During the past five years, cogging torque in HDD spindle motors has decreased drastically as designers and manufacturers have developed a better understanding of the cogging phenomenon. This paper examines various methodologies of cogging torque reduction. Timing techniques such as dead zones and tooth notching, smoothing techniques such as sinusoidal magnetization, and geometric techniques su...
