The Husqvarna 502535201 Electric Motor is a genuine OEM component designed for the PG680, PG820, PG680RC, and PG820RC floor grinders. As the core drive unit of these planetary floor grinders, this motor delivers the rotational power needed to run the grinding heads through demanding surface preparation work. Sourced directly from Husqvarna, it is built to the exact electrical and mechanical specifications of the original unit. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM-Matched Electrical Spec — Built to Husqvarna's original winding resistance and output ratings, ensuring the motor draws correct current and delivers consistent torque to the grinding deck.
- Direct-Mount Replacement — Engineered to the original bolt pattern and shaft dimensions, so this motor installs directly into the PG680, PG820, PG680RC, and PG820RC without modification to the housing or drive assembly.
- Fits PG680 and PG820 Series Floor Grinders — Compatible with both standard and remote-control variants: PG680, PG680RC, PG820, and PG820RC planetary floor grinders.
- Restored Drive Power — A failed or degraded motor causes loss of grinding head speed, uneven surface finish, and machine shutdown. Replacing it with this genuine unit restores full rotational output and consistent grinding performance.
- Genuine Husqvarna Part — Verified against Husqvarna's OEM parts catalog. Cross-reference part number 502535201 against your machine's parts diagram to confirm fitment before ordering.
The electric motor is the primary power source for the grinding deck on Husqvarna planetary floor grinders. It converts electrical input into the rotational force that drives the planetary heads, which in turn carry the tooling across the concrete surface. When the motor wears or fails, the machine loses drive power entirely or performs inconsistently, resulting in poor surface quality and potential damage to connected drive components. Replacing the motor with a genuine OEM unit ensures the grinder returns to its rated operating performance.
