Insulated Bearings	An electric motor operating on an adjustable speed drive is at risk for premature bearing failure caused by stray currents. Experience indicates using insulated bearings on both ends of the motors is the most effective way to protect the motor from destructive currents. A high level of bearing protection is especially beneficial in applications where motor maintenance and replacement are difficult.
Extended Horsepower Capability	Extended horsepower capability allows a smaller motor to run at a higher horsepower than its baseline depending on the application requirements. This provides motor users potential cost savings while achieving the same motor performance.
Insulation with Wide Thermal Capability	Critical cooling motors utilize many Class H insulation materials in its winding designs, which provides increased thermal protection. These motors operate with a very low temperature rise at rated conditions, giving them a wide thermal margin and extended motor life.
Low Vibration	A vibration level exceeding NEMA MG1 requirements provides stability and durability by prolonging motor and bearing life and helping to reduce downtime.
