Home technical articles cooling and ventilation of electric motors ic. Understanding the source of increased temperature is key to correcting the problem and improving. An electric motor s insulation system separates electrical components from each other preventing short circuits and thus winding burnout and failure.

Electric motors are often selected based upon a particular work or load requirement. Industrial motors often have an integral fan mounted on the rear of the output shaft so that it spins at the same rate as the driven load. Regardless of the application managing heat dissipation is a common theme.
