DHS Equipment supplies this part to help keep your floor grinder running at full capacity. Cross-reference part number 589686301 against your parts diagram to confirm fitment before ordering.
Key Features
- Genuine OEM Output Spec — Built to Husqvarna's exact power and torque ratings for planetary floor grinders, so grinding performance matches what the machine was designed to deliver.
- Direct-Mount Replacement — Engineered to align with the original mounting points and electrical connections on compatible machines, allowing for a clean swap without modification.
- Fits PG400, PG510I, and PG510 — Confirmed for this range of Husqvarna planetary floor grinders; verify against your machine's parts diagram using part number 589686301.
- Restored Grinding Power — A functioning motor drives the planetary head at the correct speed and torque; a worn or failed motor results in reduced surface coverage, uneven grinding, or complete machine stoppage.
- Electrical Safety Compliance — As a genuine OEM electrical component, this motor meets Husqvarna's original safety and insulation standards, which is critical for operator safety in a high-load grinding environment.
The motor is the primary drive component in a planetary floor grinder, converting electrical energy into the rotational force that powers the grinding head and its satellite discs. When the motor is operating correctly, the machine maintains consistent disc speed across varying surface loads — essential for achieving uniform results on concrete, terrazzo, and similar surfaces. A failing motor typically presents as reduced power under load, overheating, or failure to start, and left unaddressed, it can place additional strain on surrounding drive components.
