    摘要: A rotation detector has a simple structure and operates reliably to check quickly for erroneous installation as an encoder for detecting the rotation rate of a multi-rotation body that rotates for a finite number of revolutions of one revolution or more. A stator member is formed of a housing (1) and a cover (3) coupled together, and a detection window (16) is formed on an outer peripheral wall of the housing. A rotor member (2) is rotatably supported by the housing and the cover, and a rotary ring (10) arranged concentrically with the center of rotation of the rotor member is housed in the stator member. Rotation of the rotor member is intermittently transmitted to the rotary ring via an intermediate gear. According to the variation of outputs from photointerrupters that turn on or off according to the rotation of the rotary ring, an absolute position of the rotor member is detected. Also, an indicator is arranged on the rotary ring so that the indicator is visible through the detection window (1b) only when the rotary ring is in a neutral position.

    摘要: In a separate encoder (100), a scale(102) is further provided with an ABS track(106) that is arranged in parallel with an INC track(104) and a detection head(110) includes an ABS detection portion (114) that reads the ABS track(106). The separate encoder (100) includes a calculation portion (120,220,320) that obtains a yaw angle (ϕ) of the detection head(110) with respect to a scale(102) based on a gap(d) between an INC detection portion (112) and an ABS detection portion (114) and a difference amount (δ) between a position(Xinc) of the INC track(104), which is detected by the INC detection portion (112), and a position(Xabs) of the ABS track(106), which is detected by the ABS detection portion (114). The calculation portion (120, 220, 320) also obtains a signal strength(I) based on two-phase sine wave signals(Am, Bm) that are output from the INC detection portion (112). The separate encoder (100) further includes a display unit(130,220,320) that displays a plurality of yaw angles (ϕ) and the signal strengths(I) corresponding to the respective yaw angles (ϕ).

    摘要: Magnetic encoder apparatus (2) is described that comprises a plurality of magnetic sensor elements (e.g. Hall sensors) for reading an associated magnetic scale (4; 10) that produces a periodically repeating magnetic pattern. The plurality of magnetic sensor elements produce a plurality of sensor signals and an analyser (7) is provided for analysing the plurality of sensor signals to provide a measure of the position of the magnetic sensor elements relative to the associated magnetic scale (4; 10). The analyser (7) is arranged to use the plurality of sensor signals to assess the period (60) of the periodically repeating magnetic pattern sensed by the plurality of magnetic sensor elements. In this manner, the requirement to carefully match the period of the sensor elements with the periodically repeating magnetic pattern of the associated magnetic scale (4; 10) is avoided.
