How To Find AC Motor Faults

Troubleshoot your AC Motor

Common Issues

Many issues that can occur with an electric motor and specifically an AC motor. These include:


  • Bearing failure
  • Rotor problem
  • Wiring issue
  • Misalignment

Signs of a problem

Both engineers and operators can prevent complete motor failure by looking out for these signs:

  • Motor won’t power up
  • Electrical overload (sparks)
  • Low resistance (weak output)
  • Overheating or smoke
  • Excessive noise, heat or vibrations
  • Dirt and grease
  • Visible damage to the shaft, core, etc.
  • Noticeable movement between components

If you spot one or more of the above, your AC motor may soon fail. Save time and money by repairing with Kontroltek.

You may only need a bearing changed or you may require an entire overhaul and rewind. Whatever it is, the Kontroltek motors team can do it for you.

Ensuring minimal disruption, we’ll get your AC motor rewound properly and returned to you in 10 days or less (terms apply).

Read more about the rewind process.

“A pump/motor unit that supplies our largest and most time crucial production line failed late on a Friday night. I called Kontroltek at 8:30 am on Saturday and they opened their premises… By midday, it was stripped, ready to be rewound and fully overhauled. If it weren’t for suppliers [that] held them up, they would have had it back to us inside 24 hours. I ended up having it delivered on site Monday afternoon.”

“Also, worth noting they were the only one out of six companies that answered the phone. Brilliant, friendly service every step of the way. Can’t recommend enough.”
