maxon motor DC motor encoders

A large range of DC motors are already available with AVAGO encoders — both brushed DC motors and brushless designed DC motors. This is known as the ‘maxon modular system’, which allows an engineer or product designer to build up motor, gearhead and encoder combinations specifically to suit the application requirements.

The modular system has now been expanded with nine more encoder resolutions ranging from 1000 counts per turn through to 5000 counts per turn. The encoder has an optical design and can be fitted with any motor that was previously available with the 500 count-per-turn unit. It also uses the same DIN 41651 connections.

With a 5 V supply, the output signal meets EIA Standard RS 422 using an AM26C31QD driver and has a typical signal rise and fall of 10 ns. The high resolution makes it suitable for motor-positioning tasks and is particularly useful for higher power motors that will not work with magnetic-based encoder technologies.
