The Husqvarna 593559701 Frequency Inverter is a genuine OEM electrical component designed for the PG8XR and DURATIQT6 floor grinders. As a direct OEM replacement, this inverter is built to Husqvarna's exact electrical specifications, ensuring the motor receives the correct variable-frequency drive signal for consistent, controlled grinding performance. DHS Equipment supplies this part to help keep your floor grinder operating at full capacity.
Key Features
- OEM-Matched Electrical Specification — Built to Husqvarna's precise frequency and voltage output ratings, ensuring the drive system functions exactly as engineered for floor grinder applications.
- Drop-In Electrical Replacement — Engineered to connect directly to the existing wiring harness and mounting points on compatible machines, restoring original drive performance without adaptation.
- Compatible with PG8XR and DURATIQT6 — Confirmed fitment for both the PG8XR and DURATIQT6 floor grinders; cross-reference 593559701 against your parts diagram before ordering.
- Stable Motor Speed Control — A properly functioning frequency inverter delivers consistent RPM regulation across load conditions, allowing the grinding heads to maintain steady surface contact and finish quality.
- Electrical Safety Compliance — As a genuine OEM inverter, this component meets Husqvarna's electrical safety standards for variable-frequency drive circuits, helping maintain safe machine operation on the worksite.
The frequency inverter controls the speed of the grinder's electric motor by converting incoming AC power into a variable-frequency output, allowing the machine to run at precisely regulated speeds under varying load conditions. Without a functioning inverter, the motor may run erratically, fail to reach operating speed, or shut down entirely, compromising both surface finish quality and operator control. Replacing a failed unit with the correct OEM part restores the full speed-control capability the machine was designed to deliver.
