Who is Nidec?

Nidec Corporation, established in 1973, has grown from a small company with just four employees to a global conglomerate with over 140,000 employees worldwide. Nidec specializes in “everything that spins and moves,” producing a vast range of motors from small precision motors to large industrial motors. Recognized for its innovation, Nidec holds the largest global market share for small precision motors and has expanded through strategic mergers and acquisitions to meet the diverse needs of its customers.

As of September 30, 2017, Nidec completed the acquisition of Emerson Electric Co.’s motors, drives, and electric power generation businesses. In 2017, Nidec further expanded its offerings by acquiring the Leroy-Somer™ and Control Techniques™ brands. In May 2024, Control Techniques and KB Electronics transitioned to Nidec Drives, reflecting their commitment to innovation and market leadership.

Over-current faults are a common cause of drive shutdowns, necessitating a detailed examination starting from motor dynamics.

The Control Concepts Repair Process

At Control Concepts, we follow a meticulous and comprehensive repair process to ensure your Nidec drives are restored to optimal performance. Our process combines thorough inspection, detailed testing, and preventative maintenance to guarantee reliability and efficiency.

  • Thorough Inspection - We begin with a thorough inspection of the drive and terminals to identify any visible signs of wear, damage, or substandard connections. These issues can be caused by heat cycles, mechanical vibration, or improper installation.
  • Comprehensive Testing - Before applying power to the drive unit, we conduct detailed diode and IGBT tests on the input/output power sections. This step is crucial to prevent further damage from potential shorts.
  • Controlled Power-Up - We power up the unit gradually, performing amp readings and output frequency tests. Voltage is slowly increased until the rated input voltage of the drive is reached, ensuring a safe and controlled power-up process.
  • Functional Testing - If everything functions properly during the power-up, we use the drive to run a motor through basic jog functions after backing up existing programs. If the motor does not run, we check the output voltages and current ratings going to the motor to diagnose any functional issues.
  • Advanced Diagnostics - If further issues are identified, we perform dynamic tests under load conditions to simulate real-world operating scenarios. This ensures the drive performs reliably under expected conditions.
  • Preventative Maintenance - Most drive failures can be avoided through regular preventative maintenance. We recommend the following:
    • Keep the drive free of dust: Dust can impede performance and cause overheating.
    • Ensure proper ventilation: Proper ventilation prevents overheating and ensures efficient cooling of the drive components.
    • Keep everything dry and protected from moisture: Moisture ingress can lead to corrosion or short circuits.
  • Final Verification - All existing programs and configurations are backed up to prevent data loss. We conduct a final round of tests to ensure the drive is functioning correctly and meets all performance specifications. A detailed report of the repair process, including findings and corrective actions, is provided to the customer.
