The Husqvarna 502559401 PG530 Drive Motor 3Kw 4Hp 1Ph is a genuine OEM replacement motor designed specifically for the PG530 floor grinder. Sourced directly from Husqvarna, this motor is built to the exact electrical and mechanical specifications of the original unit, ensuring seamless integration with the PG530's drive system. DHS Equipment supplies this part to help keep your floor grinder running at full capacity.
Key Features
- OEM-Matched Electrical Output — Rated at 3Kw / 4Hp on a single-phase supply, this motor meets the precise power specifications Husqvarna engineered into the PG530 planetary grinding system.
- Direct-Fit Replacement — Manufactured to match the original motor's mounting footprint and shaft dimensions, this unit installs into the PG530 without adaptation or modification.
- PG530 Floor Grinder Compatibility — Engineered exclusively for the PG530, so compatibility is confirmed from the factory rather than assumed.
- Sustained Grinding Performance — A properly functioning drive motor delivers consistent rotational torque to the planetary heads, maintaining uniform surface coverage and predictable material removal rates across the work area.
- Genuine Husqvarna OEM Quality — As an authentic Husqvarna component, this motor meets the same thermal and load-handling standards as the unit it replaces, supporting long service intervals under demanding floor preparation conditions.
The drive motor is the primary power source for the PG530's rotating planetary system, converting single-phase electrical input into the rotational force that drives the grinding heads across the floor surface. When the motor underperforms or fails, the grinder loses torque consistency, resulting in uneven surface prep, reduced productivity, and potential strain on surrounding drivetrain components. Replacing a worn or failed motor with a correctly rated OEM unit restores the machine to its designed operating output and protects the integrity of the planetary assembly it drives.
