AEDB-9340-W13C
(6-Channel Optical Incremental Encoder Bundled with Codewheel)

Avago Technologies’ state-of-the-art 6-channel commutation optical encoder, the AEDB-9340 series, has been designed to enable motor manufacturers to seamlessly develop a feedback mechanism in a closed-loop servo system for Brushless DC Motor (BLDC) designs.

The optical encoder integrates channel-A, channel-B, and channel-I for positional feedback with channel-U, channel-V, and channel-W to emulate the Hall sensor feedback for rotor commutation. All these output signals are generated from the optical sensors where the number of pole-pairs can be changed easily by re-configuring the codewheel pattern without any change to the hardware design. This feature will help to significantly reduce the development time for motor manufacturers’ designs and time-to-market.

In addition, the switching accuracy is known to be much better than conventional Hall sensors where the commutation accuracy for AEDB-9340 encoder series is rated at ±1deg. mechanical. This integrated solution eliminates the use of Hall sensors in BLDC motor feedback which is not only cost effective, but also improves the overall system performance. It also reduces the total size of a BLDC motor enclosed with an integrated feedback device.

Avago Technologies’ 6-channel commutation optical encoder is available in resolutions from 1000 CPR to 2500 CPR, and the shaft diameter is available from 3 mm up to 10 mm. An alignment tool, HEDS-8952, is also available to help the system integrators to align the encoder to the motor shaft. The alignment tool, HEDS-8952, is available in 'Accessories > Alignment Tool' section.

Incremental Encoders and Code Wheels

Incremental Encoders are position feedback devices that provides incremental counts. Thus, incremental encoders provide relative position, where the feedback signal is always referenced to a start or home position. For incremental encoders, each mechanical position is uniquely defined. The current position sensed is only incremental from the last position sensed. Incremental encoders are also non-contacting optical, rotary, quadrature output device.

These incremental encoders are also called optical encoders or optical incremental encoders because they utilizes optical technology. Optical incremental encoders are highly sort after as position feedback devices due to its durability and ability to achieve high resolution. Avago's optical incremental encoders are exceptionally recognized for its reliability and accuracy.

To ensure convenience, efficiency and cost effectiveness of our customers assembly requirements, Avago offers a range of incremental encoders that are readily matched with compatible code wheels. The choice of code wheels in this category, enables Avago’s incremental encoders to perform in the most optimum position and provide the most accurate output.
