Motor overloads occur when motors are drawing too much current. The main issue with excess current is that it creates heat which degrades the insulation surrounding the conductors that creates stator magnetic field.
Professionals in the industries of manufacturing, power generation and water rely on electric motors to complete their objectives. To remain efficient, it is essential that motor-based systems stay in peak operating condition.
Electrical Insulation is used to direct current through a desired path and prevent it from flowing where it is not desired. Proper electrical insulation is critical to an electric motor’s performance and longevity.
Motor windings are conductive wires wrapped around a magnetic core; they provide a path for current to flow to create then magnetic field to spin the rotor. Like any other part of the motor, the winding can fail.
In this episode, we talk about the Charlie Brown fault zone: Insulation. Back in the 1840's, one of the first forms of insulation which was developed to prevent electricity from getting to a person or ground, was glass.
