900 HP GE Kinamatic DC Motor – 300/750 RPM – 500V

This General Electric Kinamatic 475AT is a heavy-duty 900 HP DC motor engineered for high-demand industrial applications requiring massive low-end torque. With a base speed of 300 RPM and a field-weakened maximum of 750 RPM, this motor provides an exceptional constant-horsepower range, making it the ideal solution for large-scale extrusion, rubber mixing, or metal rolling operations.

The 5CD475MA810C805 utilizes GE’s legendary square-frame Kinamatic design, providing superior power density and heat dissipation. Designed for 500V armature service and force-ventilation, this motor is built for 24/7 continuous duty in environments where downtime is not an option.

Key Highlights:

• 900 HP Industrial Capacity: Built to handle extreme mechanical loads.
• 300 RPM Base Speed: Delivers maximum torque at low speeds—ideal for primary industrial drives.
• 475AT Frame: A rugged, widely supported industrial frame with excellent parts availability.
• Serviceable Design: Features large access ports for streamlined commutator and brush maintenance.

The General Electric 5CD475MA810C805 is a massive 900 HP Kinamatic series DC motor. Built on the 475AT frame, this is one of the larger standard industrial DC frames GE produced.

The 300/750 RPM rating indicates a high-torque base speed with a 2.5:1 constant horsepower range. This specific motor is a "workhorse" for heavy industrial primary drives, such as large plastic extruders, banbury mixers, or main mill stands.
