What types of high-frequency drives do you repair?

We repair a wide range of high-frequency and high-speed motor drives, including legacy and discontinued models. Applications typically include CNC machining centers, grinding systems, robotics, automated cells, semiconductor equipment, and other precision manufacturing platforms.

What are the most common failure modes?

Common issues include IGBT failure, DC bus capacitor degradation, gate driver faults, power supply instability, and overheating due to improper cooling or load conditions. In high-speed applications, even minor waveform distortion or switching irregularities can create secondary motor issues, which is why proper validation is critical.

How long does high-frequency drive repair take?

Turnaround time depends on failure severity and parts availability. Once the drive is received, we perform a diagnostic evaluation and provide an assessment. For production-critical environments, we can prioritize evaluation to help you determine whether repair or replacement is the best path forward.

When should I replace instead of repair?

If the drive has recurring failures, obsolete components, or repeated power-stage breakdowns, replacement may provide greater long-term reliability. We provide clear, engineering-based recommendations so you can make an informed decision.
