The Husqvarna 593431301 Inverter Atv31 110V Bl 420/270 is a genuine OEM component designed for the HTC420 floor grinder. As a direct Husqvarna OEM part, it is built to the same specifications as the original unit installed at the factory, ensuring proper fit and correct electrical operation within the machine. DHS Equipment supplies this part to help keep your HTC420 performing at full capacity.
Key Features
- Genuine OEM Inverter Specification — manufactured to Husqvarna's exact electrical output and voltage ratings for the HTC420, ensuring the drive system receives the correct signal and power profile.
- Direct OEM Replacement — engineered to drop into the original inverter position on the HTC420 floor grinder, matching the original mounting configuration and wiring connections.
- HTC420 Floor Grinder Compatibility — purpose-built for the HTC420, so you can cross-reference part number 593431301 against your parts diagram with confidence before ordering.
- Restored Motor Control Performance — a functioning inverter maintains smooth, consistent motor speed control across grinding passes; a failing unit can cause erratic speed, reduced grinding power, or complete drive loss.
- Electrical Safety Compliance — as an OEM electrical drive component, this inverter meets Husqvarna's design requirements for safe operation within the HTC420's electrical system, reducing the risk of wiring stress or component damage from an incorrectly rated substitute.
An inverter in a floor grinder controls the speed and torque delivered to the grinding motor by converting incoming AC power into a variable-frequency output, allowing the operator to adjust grinding speed to suit the floor surface and tooling. This precise motor control is essential for achieving consistent surface finish results and protecting both the machine and the diamond tooling from overload. When the inverter degrades or fails, the machine may lose speed regulation entirely, produce inconsistent grinding pressure, or fail to start — making prompt replacement critical to keeping the HTC420 productive on the floor.
