Electric Motors

Inverter/Vector Duty

Inverter/Vector Duty motors designed specifically for variable speed control. They are designed to handle the additional heat generated when running at lower speeds. Vector Duty motors typically provide continuous constant torque performance across the entire speed range from zero speed to base speed.

ESR Motor Systems stocks a large range of Inverter Duty motors and has access to Vector Duty motors from most of the manufacturers we represent.
