Drive Service About Control Concept’s Motor Drive Services

We service and repair most drive types, including Variable Frequency Drives (VFDs).

Other drive types we service:

  • Mechanical
  • Hydraulic
  • Eddy-Current
  • Rotating DC
  • Electronic - DC
  • Electronic - AC

Most drives installed today for automation are variable frequency drives or VFDs. A VFD takes fixed AC voltage and frequency input, converts it to DC internally, then sends it out as variable voltage and frequency AC output.

Common Problems:

VFDs and most other drives are simple devices that are highly reliable. Problems are usually rooted in another part of the machine.

  • Loose connections
  • Cooling fan failure causing an over-temp fault
  • Drastic failure of the power semiconductors
  • Time to replace the electrolyte capacitors
  • Issues with programming
  • Circuit board

You can reduce potential problems with a little maintenance:

  • Keep the drive dust-free
  • Ensure proper ventilation
  • Keep things dry and protected from moisture
