Specifications

Small and circular shape enables the AEDS-9240 to be easily designed into housed encoders or directly mounted on to motors.

This encoder module offers a highly competitive price range. In addition, allignment tools are optional to provide easy allignment to motor shaft.

Description

The AEDS-9240 incremental optical encoder is an extension of the AEDB-9340 state-of-the-art 6-channel commutation optical encoder series. Similarly, the AEDS-9240 has also been designed to enable motor manufacturers to seamlessly develop a feedback mechanism in a closed-loop servo system for Brushless DC Motor (BLDC) designs.

However, unlike the AEDB-9340 which was designed for applications requiring high speed motor system, the AEDS-9240 is specifically designed for applications requiring low to medium resolution, such as industrial sewing machines, textile machines, elevators, as well as, low to medium resolution motor systems and  housed encoder makers.

This 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 of AEDS-9240 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.

Switching accuracy of the AEDS-9240 maintains a peformance which is known to be much better than conventional Hall sensors where the commutation accuracy 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.

This 6-channel commutation optical encoder comes in resolutions of 360 CPR and 720 CPR, and the shaft diameter of AEDS-9240  is available from 3 mm up to 10 mm.
