Motor Analysis

Improve Motor Performance and Extended Motor Life


At Enerdoor, we specialize in providing comprehensive motor analysis services to enhance the efficiency and reliability of your automation and industrial systems. Our seasoned professionals leverage advanced techniques and state-of-the-art equipment to deliver precise and reliable data on your motor performance.

With our motor analysis services, you can proactively identify potential issues before they result in costly downtime or equipment failure. We adopt a collaborative approach, working closely with you to craft customized solutions that align with your specific needs, whether it's predictive maintenance, performance optimization, or troubleshooting support.

Our overarching goal is to ensure that your automation and industrial systems consistently operate at peak performance, maximizing efficiency, and minimizing downtime.

Key Highlights of Our Motor Analysis Services:

Specialized Analysis: Our motor analysis services are designed for motors up to 690 Vac, focusing on waveform, voltage, current form, and shaft voltage directly on the motor. This in-depth analysis helps us pinpoint the root causes of premature motor failure, offering cost-effective and prompt solutions to maintain optimal motor performance and prevent production downtime.

Energy Insight: Did you know that electric motors consume 19% of the total energy produced in the United States? Moreover, over 70% of electrical energy in manufacturing, and 90% in the processing industry, is consumed by motor systems. Motors controlled by variable frequency drives (VFDs) offer energy savings but can pose challenges like overvoltage spikes, heat, and power loss.

Overcoming Challenges: We address challenges associated with VFD-controlled motors, such as square wave and overvoltage spikes (dV/dt), which contribute to heat stress, winding, insulation, and bearing damage. By eliminating these spikes using our innovative technology, the sine wave filter, we reduce heat stress, enhance motor performance, and extend motor life.

RF Noise Elimination: Enerdoor introduces a groundbreaking solution for eliminating RF noise with the sine wave filter. Unlike traditional shielded cables that contain noise, our technology eradicates RF noise, offering superior performance. The Enerdoor sine wave series covers a range from 0 to 880A, with high-frequency solutions available.
