产品介绍
Avago Technologies’ state-of-the-art 6-channel commutation optical encoder, the AEDT-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 AEDT-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.
