Description
Overview:
This Genuine Milwaukee rotor (part no. 4931479282) is the rotating core of the motor used in select Milwaukee 18V cordless angle grinders. Built with precision-wound copper windings, a laminated steel core, and a hardened steel shaft with commutator, it converts electrical power into the mechanical rotation that drives the disc. Engineered to OEM standards, it restores performance and reliability when your motor has suffered wear, overheating, or electrical faults. Designed specifically for the Milwaukee M18FSAGV115XPDB and M18ONEFSAG115XPDB, it offers correct fit and balance for smooth running, consistent power, and long service life. A genuine part is the best choice to maintain tool efficiency, protect gears and bearings, and keep brake and speed control features working as intended.
Key Features:
- Genuine Milwaukee Part for assured compatibility and performance
- Precision copper windings and laminated core for efficient power transfer
- Factory-grade commutator for stable brush contact and reduced sparking
- Balanced rotor assembly to minimise vibration and motor noise
- Durable shaft and components suited to heavy, continuous use
- Built to OEM tolerances for correct air gap and smooth rotation
- Helps restore full torque, speed control, and braking function
- Supports longer tool lifespan by reducing strain on matching parts
- Straightforward installation for experienced users and service centres
- Suitable for professional trades and demanding site conditions
Typical Applications:
Use when an angle grinder shows power loss, excessive arcing, abnormal heat, vibration, or motor failure due to worn or damaged windings. Ideal for restoring performance on cutting, grinding, beveling, and surface preparation of metal, masonry, and similar materials. Suits workshop maintenance, construction sites, fabrication, utilities, and plant or tool hire fleets.
