Electric motors and generators are vital to the mining industry, allowing equipment such as mills, crushers, hoists, pumps, and haulers to operate. Tools and machinery for this work must be durable and reliable to enable seamless production in even the harshest of environmental conditions. When motors or generators do fail, this can cause significant interruptions to your operation for equipment repair, which results in lost revenue or even worker injury. Periodic maintenance will help your mining operation avoid costly downtime and replacement parts, as well as unsafe working conditions.

As an authorized dealer, service provider, and warranty center for the majority of big-name motor and generator manufacturers, Renown Electric Motors & Repair Inc. understands what it takes to keep your AC and DC motors and generators running at their best. Since 1984, we have provided electrical and mechanical motor and generator preventative maintenance programs and engineering support, repair, remanufacture, and overhaul services to diverse industries across the world.

Motor & Generator Maintenance & Repair in the Mining Industry

Mining Industry

Considering the ways in which mining operations can go awry, regular electric motor and generator maintenance is a necessity to help assure equipment life span and reliability. To that end, Renown Electric provides the following services:

  • Preventative maintenance. Inspecting machines periodically helps identify potential operational and performance issues before they become a challenge.
  • Winding analysis. We’ll check your equipment’s dielectric strength, or its insulation value in protecting against contaminants and spikes in voltage, to determine if replacement or overhaul is required.
  • Motor and generator rewinding. Motor and generator rewinds are an economical way to restore a motor or generator to like-new efficiency and enhance horsepower output.
  • Bearing maintenance and replacement. Bearings, as load-carrying components, usually wear out quickly compared to other motor parts, so regular bearing inspections can prevent unexpected motor breakdowns.
  • Inverter/drive maintenance and repair. Electric motor drives enable control over the speed and torque of a motor. Carrying out predictive or preventative maintenance on these drives reduces damage risk within a machine and provides smooth operational performance.
  • Diagnosing and repairing motor drives. Renown Electric’s wide range of services includes diagnostics for AC and DC inverters and drives, as well as any necessary repairs and load testing.

Electric Motor & Generator Repair Is Crucial to the Mining Industry

The mining industry is moving to AC motors with variable frequency drives (VFDs) to regulate their speed through analog controls. These VFD motors utilize cooling systems to maintain performance quality, pulling heat from power-generating semiconductor components to increase the motors’ life span. Their compact footprint makes them suitable for small spaces or harsh conditions in mining applications.

High-voltage drives are efficient for mining tasks. In the power delivery systems of large, soft-starting mill motors, these drives reduce stress by safeguarding against low current inrush and voltage dips. They effectively control torque, speed, and power within a motor to optimize operations and enhance equipment longevity.

To make sure such equipment remains highly functional and safe to use, Renown Electric inspects VFDs and soft starters, tracking a drive’s output and input over time. Our team gathers these measurements to set up a baseline of capacitor performance. This allows us to pinpoint any variations in ripple, DC bus voltage, or the workings of internal drives to avoid unexpected downtime and lost revenue.
