Electric Motor Repair for Black & Decker Lawnmowers (P/N: N600598 / N683425)
Original Black & Decker brushed electric motor assembly, part number N683425 (P/N N600598 is stamped on the stator housing itself) for corded rotary lawnmowers. The module comes as a complete assembly with an integrated drive mechanism and a pre-installed poly-V belt. Used to replace a burnt-out motor or a broken drive.
Drive and Belt Features:
- Integrated Belt 7PJ522 / NA278294: A 7-rib poly-V (multi-rib) belt marked 7PJ522 (length 522 mm, PJ profile) is installed inside the module.
- Important Repair Information: Officially, the manufacturer Black & Decker does not supply the NA278294 drive belt as a separate spare part, recommending instead to replace the entire motor assembly (N683425). However, the presence of the pre-installed belt in this assembly allows for "out-of-the-box" mower restoration without searching for third-party alternatives.
Compatibility (Black & Decker Lawnmower Models):
The N600598 / N683425 motor unit is the standard assembly for the following corded lawnmowers:
- Black & Decker BEMW481BH
- Black & Decker BEMW481ES
- As well as related Black & Decker BEMW series corded mower models with similar cutting widths.
Key Advantages:
- Original OEM Module: The factory P/N N600598 marking guarantees a 100% match for mountings, dimensions, and electrical connectors.
- Ready for Installation: Does not require separate pulley pressing or belt tensioning — supplied fully assembled.
- Overheat Protection: An integrated thermal relay automatically cuts power if the blade jams or during overload in thick grass.
