Dunkermotoren AE38 Absolute Encoder

The Dunkermotoren AE38 is a battery-free absolute encoder that reports true shaft position the instant the drive powers up — with no homing move or reference run before the axis can be trusted.

It integrates inside the motor’s own profile housing rather than bolting on as a separate unit, without an extra enclosure, and feeds position straight to the internal Dunkermotoren controller. Its multiturn count is held by Energy Harvesting — power drawn from shaft rotation — so there is no backup battery to monitor or replace.

The same encoder suits Dunkermotoren’s BG brushless DC motor range, with overall length varying by motor frame, so a drive can be specified with absolute feedback built in from the outset rather than added later.

It fits positioning and motion-control tasks where the axis must come up already referenced — automated machinery, handling and actuation duties that can’t afford a homing cycle at every power-up.
