Technical Data
V-Ring Seal
V-Ring Seal to avoid the liquids and dust inlet in the motor.
Capacitor
With runner capacitor, runner and permanent capacitor or permanent capacitor.
Cooling System
• The cooling system (fan, non-drive end shield and fan cover) is designed to minimize noise level and improve thermal efficiency.
• Steel plate fan cover provides high mechanical strength, corrosion resistance and extended lifetime.
Cast Iron Frame
• FC-200 (EN GJL 200) cast iron frames meeting impact level IK08 (5J) ensuring superior mechanical strength for the most demanding applications.
• Solid motor feet providing excellent rigidity, allowing easier alignment and installation.
Centrifugal Switch
The starting system of W40 motors was completely redesigned to improve functionality, thus increasing system reliability and lifespan.
