TITAN Vertical Motors

Nidec is continually improving the TITAN motor line to meet customer needs for performance, efficiency and reliability. The new TITAN 5812/5813 verticals are manufactured using a cast iron frame instead of a fabricated frame enabling production of the winding and frame assembly in parallel rather than in series. This reduces production time and ensures faster delivery to customers. TITAN motors also incorporate the latest, improved rotor fabrication process for extra reliability.

The cast iron frame 6813 TITAN vertical motor is designed for applications in the water/wastewater, mining, and oil and gas industries. The new frame construction, built with higher horsepower ratings, delivers a motor with less design.
