AC Inverter / Vector Duty Motors

Industrial electric motors are available for most general purpose applications and processes. However, some AC Variable Speed applications require constant torque at zero speed. Inverter/Vector motors are designed specifically for adjustable speed applications in a standard NEMA Frame motor. Additionally, the AC Inverter/Vector Motors can be ran across the line for bypass operation and can deliver a 1000:1 Speed Range in a standard TENV or TEBC Enclosure.
