The newly developed Class H TEFC vertical hollow shaft that is suitable for nearly all applications. The Multi-Duty line is ideal for nearly every application but it serves most advantages in replacing the WPI design within the agriculture irrigation market. The TEFC design has THREE major advantages. First, air is not drawn into the motor for cooling and therefore the windings stay clean and dry. Two, the windings are protected against direct entry of wind driven rain, directed spray, and splash from the ground. And three, insects and other vermin cannot enter the motor.
