Weg General Purpose Motors W40

Description

The W40 motor was designed to operate in environments where dirt and humidity are minimal. It has torque with Design "B" for frames 254 to 444/5T and Design "A" for frames 447/9T and 5010/11T. They were especially designed to allow maximum ventilation, cooling and performance in a great variety of applications.
