Frequently asked questions

What is the acceptable range for motor insulation resistance?

An insulation resistance of 100MΩ or greater is considered good. Values between 10MΩ and 100MΩ indicate aging and require regular checks, while values below 1MΩ indicate the motor should be replaced.

How long must one wait before touching terminals after cutting the power?

One must wait at least 5 minutes after cutting the power before touching the terminals, as high voltage may still exist between the power terminals.

What voltage should be used to measure motor insulation resistance?

The insulation resistance should be measured using a megohmmeter with a DC500V output.
