Durable Cast Iron end shields are machined to close tolerances for exact alignment of bearings and rotor. Relubable bearings are easy to access in the front and back end shields. Non-hygroscopic Class F insulation system consists of Class F and H materials. All windings are tested before and after insertion into the frame to NEMA MG-1 high potential voltage standards to assure electrical integrity. Bearings are sized to provide high load capacities and low temperature operation for long service life.
Bearings are vacuum degassed for maximum durability.
Cast iron bearing inner caps provide accurate alignment and prevent bearing contamination. Precision cast aluminum conductor bars on the rotor keep vibration to a minimum and service life to a maximum. All rotors are dynamically balanced to meet or exceed NEMA standards Diagonally split conduit box exceeds NEC and NEMA volume standards and can be rotated in 90 degree increments. Reliance Electric, the industry leader in energy efficient products, introduced the E-Master AC motor in 1993 as cost effective alternative to meeting the federal regulations for minimum efficiency. The E-Master AC motor complements our XE premium efficient design and has the same performance characteristics you expect from Reliance Electric.
