Key Features
- Correct Electrical Specification — Manufactured to Husqvarna's OEM capacitance and voltage ratings, ensuring the motor receives the precise starting and running support it was engineered for.
- Direct Drop-In Replacement — Built to match the original mounting configuration and terminal connections, allowing straightforward installation without modification.
- Broad Floor Grinder Fitment — Compatible with HTC280, PG280, PG450, HTC450, PG510I, PG510, and HTC510 floor grinders, covering a wide range of Husqvarna planetary grinding platforms.
- Restored Motor Starting Performance — A functioning capacitor delivers the energy burst needed for reliable motor start-up and smooth running; a failed unit causes hard starts, reduced torque, or complete motor failure to start.
- Electrical Safety Compliance — Using the correct OEM-rated capacitor helps maintain the machine's designed electrical safety margins, reducing risk of motor damage or overload in the grinding circuit.
The capacitor in a floor grinder plays a critical role in the motor's electrical circuit, storing and releasing the energy needed to initiate motor start-up and support consistent running performance. In single-phase motor configurations commonly found in floor grinding equipment, the capacitor shifts the electrical phase to generate the torque required to bring the motor up to speed. When a capacitor degrades or fails, the motor may struggle to start, run with reduced power, overheat, or refuse to turn over entirely — all of which halt productive grinding operations and can place additional strain on the motor windings.
