Original Bosch armature / rotor — part no. 1617000690. Direct replacement rotor (230 V) for Bosch SDS‑plus rotary hammers; precision‑wound copper coils and balanced shaft make it a straightforward drop‑in motor rotor (Bosch power tool parts diagram position 803).

Fits (examples — verify the 10‑digit type number on your tool’s rating plate before ordering): GBH 3‑28 DRE / GBH 3‑28 DFR (multiple type variants such as 3 611 B3A 000 and 3 611 B4A 090) and GBH 3000.

Notes for installation: this rotor is the 230 V version and many listings show it supplied with its bearings or paired with the matching fan and field; the common front/rear ball bearing size used with these rotors is 7 × 19 × 6 mm (inner Ø × outer Ø × width) — check your exploded view to confirm whether you’ll receive the rotor with bearings or need to reuse/replace them separately.

Short, usable replacement when you need the original Bosch rotor that matches the factory parts diagram and type numbers listed above.
