Three-phase motor W22

460 Vcast ironcast iron frame

The W22 IEEE 841 motors were especially designed to operate in petrochemical and chemical industries. The motor has cast iron frame, flexible mounting, solid and whole feet, low noise levels, anticorrosive internal coating and high efficiency. Ventilation System The ventilation system design of the W22 line provides lower noise levels and allows a better distribution of the air flow over the motor, which minimizes hot spots on the surface and increases reliability and useful life. Terminal box and eyebolts positioned so as to reduce the air flow dispersion; Lower operating temperature on the bearings, resulting in longer lubrication intervals; Low noise levels. Frame The frame design reduces the air flow dispersion and contributes to increasing the heat exchange between the motor and the environment, reducing hot spots on the frame surface and extending the bearing lubrication intervals. Endshields Designed to improve the cooling and provide lower operating temperatures of the bearing, in addition to extending lubrication intervals. D-Endshield Bearing hub displaced outwards the endshield; Lower operating temperature; Robust structure. ND-Endshield Optimized air flow; Reduction of noise levels; Robust structure to prevent machine deformation.
