DHS Equipment provides this part to help keep your floor grinding equipment running at full capacity.
Key Features
- Genuine OEM Drive Integrity — Sourced directly from Husqvarna, this motor matches the original output characteristics and mounting configuration of the factory-installed unit — no compromises on power delivery or rotation spec.
- Exact-Fit Replacement — Engineered to drop into the same motor bay as the original, with matching electrical connections and mounting points for a straightforward swap on compatible machines.
- Broad Floor Grinder Compatibility — Confirmed fitment across the HTC510, PG450, PG510I, and PG510 floor grinder models, covering a wide range of planetary grinding applications.
- Restored Grinding Performance — A failed or worn motor leads to inconsistent disc speed, loss of surface coverage, and grinding head stall. Replacing it with this OEM unit restores consistent torque and grinding head operation.
- Verified Part Number — Cross-reference 585191901 against your machine's parts diagram to confirm correct selection before installation.
The motor is the primary drive component in a floor grinder, converting electrical power into the rotational force that turns the grinding heads or planetary disc assembly. When the motor degrades or fails, the machine loses the consistent rotational speed needed for uniform surface preparation — resulting in uneven finishes, reduced grinding pressure, or a complete loss of function. Replacing this component with a genuine OEM unit restores the correct power output and ensures the grinder performs as Husqvarna intended across concrete grinding, surface prep, and polishing applications.
