Bafang BBS03/BBSHD/G320 1000W 48V/52V motor core assembly. Complete stator‑rotor unit available; stator and rotor can also be purchased separately. OEM‑spec repair part for winding burnout, demagnetization & power attenuation.
This motor core is the energy‑conversion electromagnetic core component for Bafang BBS03, BBSHD and G320 1000W high‑power mid‑drive e‑bike motors. Options available: Complete motor core (stator + rotor assembly), or purchase stator and rotor individually as separate spare parts. It is an original‑spec replacement for motor faults including winding burnout, insulation failure, rotor demagnetization and power attenuation. Compatible with stock 48V and upgraded 52V motor versions.
The stator adopts precision‑laminated 0.35mm high‑magnetic‑permeability silicon‑steel sheets, with distributed windings made of large‑diameter oxygen‑free copper enameled wire. Winding turns and wire diameter strictly match original high‑power motor parameters to achieve low iron loss, low copper loss and high energy‑conversion efficiency. Fully encapsulated with H‑class high‑temperature‑resistant insulation material for anti‑breakdown and anti‑aging performance, adapting to long‑time high‑temperature working conditions of high‑power motors. Mounting holes, inner / outer diameter and wire outlet position fully follow factory dimensions, enabling direct installation without extra modification to restore original 1000W output performance.

✅ Multiple Purchase Options: Get full stator‑rotor motor core assembly, or buy stator or rotor separately, target only the damaged component to save repair cost.
✅ OEM‑Spec Dimensional Match: Mounting holes, inner/outer diameter and wire‑outlet position consistent with original parts. Direct fit with no machining or modification required.
✅ Low‑Loss Electromagnetic Performance: 0.35mm silicon‑steel laminations reduce iron loss; thick oxygen‑free copper windings lower copper loss for high‑efficiency power conversion under continuous high‑torque load.
✅ H‑Class High‑Temperature Insulation: Anti‑breakdown and anti‑aging stator encapsulation, stable performance under sustained high‑temperature working conditions for 1000W high‑power motors.
✅ Targeted Repair Solution:
• Replace stator only: for burnt windings, short‑circuit, insulation failure.
• Replace rotor only: for magnet demagnetization, rotor damage.
• Replace full motor core: for severe combined damage. Ideal spare parts for ebike repair shops and DIY motor rebuilders to restore original 1000W power output.
‑ This motor core / stator / rotor fits only Bafang BBS03, BBSHD, G320 1000W mid motors. Not compatible with M‑series or BBS01/BBS02 motors. ‑ Professional mid‑motor disassembly‑assembly experience is mandatory for installation. ‑ Confirm motor model and working voltage (48V / 52V) before placing order. ‑ Select the correct variant: complete motor core / stator only / rotor only according to your actual damaged part.
