The motor megger test, also known as the insulation resistance test, is a diagnostic procedure used to evaluate the integrity of the insulation in an electric motor. This test provides a quantifiable measure of the insulation resistance, typically expressed in hundreds of megaohms, or even gigaohms. You can also test the rigging and field coils separately, from the armature itself.

Megging a motor is a term used to test a 3 phase motor to check the resistance and condition of the motor windings using a. You can also test the rigging and field coils separately, from the armature itself. This test provides a quantifiable measure of the insulation resistance, typically expressed in hundreds of megaohms, or even gigaohms. For dc generators and motors, you’ll need to raise the brushes, as shown in the figure below.
