NEMA Premium efficiencies reducing cost

Mining and Minerals innovation

 A Mile-High Problem

The existing application incorporated a 50 HP Division 1 Class II Group F explosion proof motor with a service factor of 1.0.  Initially, upon commission of the mine, all went as planned; however, as production picked up, increased downtime was experienced causing production losses. The motor had been replaced three times with the same brand based on nameplate data.   


Mining & Mineral Innovations

  • Crusher Duty Motors
  • IEC & NEMA High Efficiency Motors
  • Medium Voltage Drives
  • HERA® Gear Drives
  • ATEX & Hazardous Duty® Motors
  • HubFlex® Shaft Couplings
  • HERA® Gearmotors
  • Variable Speed XP Motors


Exceptional Solutions that Solve Problems

We offer an array of exceptional solutions for the mining and minerals industry. Our innovations include high efficiency ATEX and Hazardous Duty® motors, helical bevel high efficiency gear drives, Solid state starters, and medium voltage VFDs that are “Performance Matched” to our motors. PMAC integrated motors provide IE4 efficiencies for a myriad of mining applications. 

A Blue Chip Series® XRI®-XP Division 1, Class I & II, Groups C, D, F & G motor with a 1.15 Service Factor was offered.  The mile-high altitude, higher temperatures on high production days, and temporary overloads due to voltage or load variation had caused the exiting motor to exceed its nameplate rating and fail.  The Marathon® motor operates well within its design parameters.  An added advantage is the NEMA Premium® efficiencies that reduce operating cost.



Value Proposition

We have a developed reputation for conservative motor designs, highly engineered motion control, and power transmission products used in a vast array of commercial and industrial applications around the globe.

Market leading solutions that reduce energy consumption, improve process throughput, provide sustainability, increase productivity, and uptime are at the heart of what drives our world.

The Blue Chip Series® XRI® family of motors have led the motor industry for over 30 years in “Mission Critical” applications where NEMA Premium® IE3 efficiencies and severe duty construction are required.

BlackMAX® and BlueMAX® inverter duty motors with the patented MAXGUARD® insulation system have stood the test of time as the choice of the design engineer when specifying variable speed motors for the most demanding applications. With unlimited lead length and protection against the potential destructive forces associated with the high switching frequencies of today’s PWM drives, you can be assured of reliable and dependable performance year after year.  

Today, we build on our 100-year-old legacy of innovative and efficient designs by the joining of magnetics, motors, and controls into a single leading technology. This allows for unparalleled power densities, unprecedented performance, and unmatched efficiencies.

SyMAX® and NovaMAX PMAC radial flux motors allow you to imagine and implement possibilities that no conventional induction motor or competing variable speed technology can provide in a host of commercial and industrial applications.

High efficiency mechanical solutions are at the cutting edge of what we do best. We are recognized for producing reliable solutions that solve problems in critical applications where performance is crucial.
