The Husqvarna 505155102 Rotor Assembly 230V Dm280 is a genuine OEM component designed for the DM280 concrete core drill. As a direct Husqvarna OEM part, it is manufactured to the exact electrical and dimensional specifications of the original, ensuring proper motor function is fully restored. DHS Equipment supplies this part to help keep your core drilling equipment operating at its best.
Key Features
- OEM-Matched Electrical Specification — Wound and balanced to Husqvarna's original 230V output spec, ensuring correct motor speed, torque delivery, and thermal performance in the DM280 drill motor.
- Exact-Fit Assembly — Built to the original rotor dimensions for direct installation into the DM280 motor housing, with no machining or adaptation needed to achieve proper shaft alignment and bearing seating.
- DM280 Core Drill Compatibility — Confirmed fitment for the DM280 concrete core drill, giving you confidence that this is the correct assembly for your machine before ordering.
- Restored Drilling Power — A correctly functioning rotor delivers consistent rotational force to the drill bit. A worn or failed rotor causes loss of power, overheating, and motor seizure — replacing it with this OEM assembly restores full drilling capacity.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna's OEM supply chain, this rotor assembly meets the same standards as the unit that left the factory, protecting the integrity of your DM280 motor.
The rotor is the rotating core of the drill motor's electric drive system. It works in conjunction with the stator to generate the electromagnetic force that spins the drill spindle and drives the core bit through concrete. When a rotor wears out or fails — typically from heat buildup, contamination, or extended use — the motor loses torque, runs roughly, or stops turning altogether. Replacing this assembly with a correct OEM unit brings the motor back to its original power output and protects surrounding motor components from secondary damage.
