About
The W22 Medium Voltage motors provide the same advantages as the W22 Low Voltage line, but with voltages of 1.1kV to 6.6kV.
- Reduced vibration and noise levels
- Higher efficiency levels
- Easy maintenance
- Frame with high mechanical strength, enabling maximum cooling
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.
Terminal Box
The increase in the internal space of the terminal box simplifies the access to the terminals, ensuring easy and safe electrical connections during the installation and maintenance of the motor.
•The connection system of the terminal box allows easy modification of the motor mounting on the larger frames (IEC 225 / NEMA 447T and above), reducing the time to perform the change and the number of motors in stock.
