AC motor W22

three-phase380 V400 V

With cast iron frame, flexible mounting, solid and whole feet and lower operating temperatures, the W22 motors are perfectly suitable for a great variety of industrial applications and meets the efficiency level according to IEC 60034-30-1. 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. The fan cover made of cast iron offers greater impact resistance IEC 160 / NEMA 254T and larger and all IEEE 841 (IEC 63-132 / NEMA 143T-215T standard W22 are heavy gauge stamped Steel) Terminal box and eyebolts positioned so as to reduce the air flow dispersion Lower operating temperature on the bearings, resulting in longer lubrication intervals Frame The frame design reduces the air flow dispersion and contributes to increased 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 toward the outside of the endshield Lower operating temperature Robust structure to minimize vibration and increase heat dissipation ND-Endshield Optimized air flow Reduction of noise levels Robust structure to minimize vibration
