Rotary encoder control

Neil Cameron · Apress eBooks · 2020

A rotary encoder detects rotation of the center shaft and is used to control machinery position and motor speed, audio volume, the cursor position on an LCD (Liquid Crystal Display) screen, or simply LED brightness. For example, in Chapter 1 (Internet radio), the radio station and volume were selected by turning a rotary encoder. The incremental rotary encoder has 20 positions, and the rotor is continuously rotated clockwise or anti-clockwise to increase or decrease a control variable. The rotary encoder has two pins, termed A or CLK (clock) and B or DT (data), and a common pin. As the rotary encoder rotor is turned, pins A and B each make contact with the common pin, which generates square waves, but as the pins are offset, the square waves are 90° out of phase (see Figure 19-1). The number of square wave pulses indicates the extent of the rotation, which is measured on either pin A or pin B.

Rotary Encoder Calibration

Šindelář, Michal · Brno University of Technology Digital Library (Brno University of Technology) · 2018

Manufacturer of an encoder gives an information about maximum error level of the measured position and the magnitude of the angle deviation for each single position is unknown. The calibration provides an error map which can be used for correction of actual measured angle value. Hence, the measurement accuracy for each position is significantly increased. Presented method provides on-axis self-calibration and does not require any external angle standard. It is based on the interpolation of correct angle position for each count of the encoder.

Autofocus laser rotary encoder

Jihua Zhang, Lilong Cai · Applied Optics · 1998

A laser incremental encoder with autofocus operation isproposed. In the encoder, an optical read head focuses three laserbeams upon a disk with a scaling grating. The scaling grating is areflection grating for which the height difference between adjacentpixels is one quarter of the wavelength of the laser. Each of thetwo laser beams is focused onto one of the two sections of thereflective grating, whereby the pitch of the grating can be detected byinterferometric reflection. The third beam acts to provideautofocus and is reflected from a smooth part between the two sectionsof the reflective grating. Therefore the encoder is less sensitiveto the gap between the optical read head and the scaling grating, andno precision adjustment is required. Also, the reading data arefree from the vibration and waviness of the grating surface. In theexperiments an encoder disk was fabricated from a wafer by lithographictechniques. The encoder with an 18-mm radius of the disk can reacha resolution of 2(16) = 65,536 pulses per revolution withoutelectronic interpolation.

Self-calibratable rotary encoder

Tsukasa Watanabe, Hiroyuki Fujimoto, Tadashi Masuda · Journal of Physics Conference Series · 2005

In the National Metrology Institute of Japan (NMIJ)/AIST, a rotary encoder calibration system was developed as the national primary standard for an angle, and a highly precise standard calibration service has been supplied from 2003. The source of uncertainty that influences most greatly in calibration is the attachment error (eccentricity) of a rotary encoder. Even if users get the calibrated rotary encoder, the error when attaching in using apparatus cannot be estimated. In NMIJ, we developed the new rotary encoder that can be calibrated by rotary encoder itself. Its mechanism is very simple; some reading heads are arranged at the equal angle interval around a scale disk. The calibration curve that contains not only all graduation lines deviation but eccentricity can be obtained by analyzing in series the signals acquired from heads. In order to check the performance of this epoch-making rotary encoder, we set up this system on the national primary standard and compared this self-calibration data with the data by using the primary standard system. The accuracy for 0.5'' or less could be acquired. Since this method is applicable also to a small rotary encoder, it is expected that the self-calibratable rotary encoder be used in many angle control instruments.

Polarimetric 360° absolute rotary encoder

Mark Johnson · Advanced Optical Technologies · 2022

Abstract Encoders of angle based on rotating polarizers suffer from 180° ambiguity due to their inherent twofold rotational symmetry. This restricts their applications in motor and machine controls. We show that the ambiguity can be resolved through a geometrical mapping from a plane to a conical surface. Seen from the local surface normal, one full rotation of the cone gives one half rotation of the polarizer axis. With appropriate transmission or reflective optics and multiphase detection, we build high resolution, moderate accuracy, absolute-angle encoders without 180° ambiguity. Polymer birefringent retarders can be used similarly.

MEMS rotary strapdown INS with low-resolution rotary encoder

Yifan Qin, Jizhou Lai, Qian Wu et al. · Gyroscopy and Navigation · 2016

The paper focuses on two problems of conventional attitude algorithm in MEMS rotary SINS. One is that the yaw error diverges, and the other is that the high-resolution rotary encoder is relied on. In order to solve the problems mentioned, an improved attitude algorithm in MEMS-RSINS aided by compass/rotary encoder is proposed and detailed. Then simulation is conducted to prove the validity of this improved attitude algorithm.

Features of a magnetic rotary encoder

K. Miyashita, T. Takahashi, Manabu D. Yamanaka · IEEE Transactions on Magnetics · 1987

A magnetic rotary encoder has several features different from those of an optical one : simple structure, quick response, good resistance to humid and dirty environments, easiness to get multi-functions and small power dissipation. According to those features, magnetic encoders are expected to be widely used.

Development of Novel Rotary Magnetic Encoder

Kai-Yang Peng, Jen-Yuan Chang · 2019

Abstract This paper discussed the development and validation of a new rotary magnetic encoder for measurement of spindle’s axial displacements. The novelty of this work is on the design of permanent magnets as the magnetizing source to produce alternative magnetic polarities on ferromagnetic material electroplated on disk/ring-like flange that is attached to the targeted spindle shaft. Through mechatronics integration and numerical finite element parameter studies, the optimal combination of the magnetizer design parameters with consideration of the arrangement of magnetoresistive (MR) elements is reached to produce the novel encoding magnetic patterns for the axial displacement measurements. The effectiveness of the proposed method is further validated through calibrated experiments leading to the conclusion of reaching 10um accuracy performance in the measurement of the spindle’s axial elongation.
