DC to AC Upgrades

Cost-effective life extension
for valuable DC machines

Full DC to AC machine upgrades

As true experts in electric industrial motors, drives, MG sets, and control systems, FLANDERS can upgrade nearly any machine you have from DC to AC:

  • Draglines
  • Electric rope shovels
  • Haul trucks
  • Auxiliary mill machines
  • Milling roll tables
  • Cranes
  • Plastics extruder lines
  • And many other machines

If your DC machine is ready for a rebuild or a tear-down for relocation, don’t miss the opportunity to upgrade it to AC power.

A win for power, control,
productivity—and budget

  • Performance. Boost horsepower, torque, and speed when you need it.
  • Safety. Keep your people safer, with better machine control and fewer maintenance hours.
  • Efficiency. Improve energy efficiency by as much as 15%.
  • Structural protection. Reduce stress on your equipment, with more responsive power control.
  • Uptime. Increase machine availability due to reduced maintenance requirements.

Our DC to AC upgrades can also extend the useful life of your industrial machines by 30% or more for a fraction of the cost of a new machine—a smart choice at any time, but especially when budgets are tight.

FLANDERS mining-duty AC motors and drives

FLANDERS AC motors and drives for mining machines are engineered and built specifically for mining duty; they’re not systems simply adapted from other industrial applications. So you can be confident they’ll withstand extreme conditions.

Plus, we offer the best warranties in the industry.

Converting motors and drives from DC to AC

Pack more power in the same footprint, frame size, and shaft height

We can readily upgrade your machine to AC power without modifying the machine’s fit-for-purpose DC motor frame, and we have a couple of options for how to approach it.

FLANDERS can handle the start-to-finish DC to AC upgrade of motors, drives, and controls, or we can upgrade the motor and leave it to your team or a partner to make the corresponding DC to AC drive upgrade.

Our engineering team has designed quite a few higher-performance, FLANDERS-original motors and drives, which we custom manufacture. We also offer systems by Siemens—we’re an authorized Siemens Solution Partner—as well as Toshiba, Allen-Bradley, and other manufacturers.

 

Cooling systems

FLANDERS also designs cooling systems for our DC to AC retrofits. The rotating pieces in DC and AC motors heat differently, so they need different cooling systems. Airflow is a critical design and engineering consideration if we’re using the same motor frame.

Additionally, we can convert air-cooled power systems to water-cooled systems to reduce maintenance, energy consumption, and noise.

“Depending on the machine and application, when we convert a DC to AC, it can make sense to switch from an air-cooled to a water-cooled system. That enables us to seal the cabinet and eliminate filters that would otherwise need to be changed during routine maintenance.

In some cases, we can also move heat exchangers from inside to outside the housing and eliminate a couple of intake fans, which reduces both energy consumption and noise. So when we’re doing DC to AC conversions, we really want to look at the big picture.”

Our pioneering DC to AC dragline upgrades

High-efficiency, fast ROI systems built to last for 20 years

FLANDERS developed the world’s first full DC to AC dragline upgrade, a major boon for surface mining operations looking to get more productivity and longer life from older machines that have DC motion motors, MG sets, and electrical systems.

This full machine conversion includes ultra-low-maintenance, high-efficiency drives that also give you better control.
