The Dunkermotoren MR1 delivers integrated position and speed feedback from inside BG75 dCore and BG95 dCore motors, with 1,024 ppr (4,096 cpr) resolution over an internal A/B/I interface — all without adding a separate encoder housing or mounting point.

With the MR1 drawing its supply directly from the motor's own internal electronics, there's no separate encoder cable, connector, or power rail to specify, wire, or fault-find. Feedback is available as soon as the motor itself is powered and connected to the drive.

This makes the MR1 well suited to closed-loop motion control applications that need reliable position and speed feedback in a compact footprint, including automation, robotics, and process machinery built around BG75 dCore or BG95 dCore motors.

For applications where a single encoder isn't sufficient, the MR1 can be combined with an external RE30-2-1024 encoder to build a redundant safe feedback system, extending the same motors into safety-rated position sensing.

FAQs
The MR1 is factory-integrated inside the BG75 dCore and BG95 dCore motor housing, drawing power from the motor's own internal supply and requiring no separate encoder cable, connector, or mounting point. Standalone encoders such as the RE30 are externally fitted, run on their own 5Vdc (or optional 24Vdc) supply, and need their own wiring and, in open form, a protective hood rated IP54 or higher. Choose the MR1 for a compact, pre-wired feedback solution on dCore motors; choose an external RE-series encoder where the motor doesn't support integrated feedback or a field-serviceable encoder is preferred.
The MR1 delivers 1,024 pulses per channel per revolution (ppr), resolving to 4,096 counts per revolution (cpr), over an internal A/B/I interface — giving fine-grained position and speed feedback suitable for demanding closed-loop control.
The MR1 is purpose-built for the Dunkermotoren BG75 dCore and BG95 dCore motor series only; it is integrated into these motors during manufacture and is not available as a retrofit or standalone unit for other motor families.
The MR1's A/B/I interface includes an index (I) channel that outputs one pulse per revolution, giving the drive a reliable zero reference point. This allows the system to home repeatably to the same mechanical position on every power-up or reset, which is important for applications requiring precise absolute positioning after a homing routine.
Yes. Where a single encoder isn't sufficient for the application's safety requirements, the MR1 can be paired with an external Dunkermotoren RE30-2-1024 encoder to build a redundant feedback arrangement, extending BG75 dCore and BG95 dCore motors into safety-rated position sensing.
The MR1 draws 11mA input current from the motor's internal supply and outputs a maximum of 40mA, with a low-state output voltage of 0.2Vdc maximum and a high-state output voltage of 5Vdc minimum. This output drives most controller inputs directly without additional interface electronics.
No. Because the MR1 is built inside the motor rather than fitted externally, it has no separate housing, connector, or mounting point of its own — the drive envelope of the BG75 dCore or BG95 dCore motor is unchanged. When housed within the motor's profile housing, the integrated encoder shares the motor's own environmental protection rating (up to IP65 on BG65-profile dCore motors), rather than requiring a separate protective hood as external RE-series encoders do.
The MR1 suits closed-loop motion control applications needing reliable position and speed feedback in a compact footprint — including automation, robotics, and process machinery built around BG75 dCore or BG95 dCore motors. As the MR1 is only available pre-integrated into these motor series, selection is effectively determined by the motor choice; for help confirming compatibility or evaluating redundant feedback options, contact Powerbox at sales@powerbox.com.au or 1800 251 380.
