The control system of a typical open-loop VVVF drive system generates an output
voltage with a constant V/f ratio, to provide approximately constant motor air-gap
flux in the region between zero speed and the base speed (50 Hz).

That speed is known as the base speed. Base speed will be achieved if the shunt
field current is about 85-90% of the ratio of line voltage to field resistance and
with rated (specified) line voltage at the armature terminals. 9.2.2.1 Speed

The corner speed is referred to as the base speed. In traction motor design, two
important parameters, maximum power and extended speed ratio x, which is
defined as the ratio of its maximum speed to its base speed, must be determined
first.
