5.7 Current and magnetization handling
The DC brake can be used to hold the motor in place
(nominal torque at nominal slip). It can be also used to keep
the motor warm in places with high humidity and to speed
up the generation of rotor flux. Rotor flux is needed in the
induction motor to generate torque.

The current that is needed to make the nominal flux is
defined by the magnetization current parameter but,
depending on motor size, nominal flux takes a different time
to produce after start command.
Giving a higher current on start to the motor will decrease
the time when the motor is able to generate nominal
torque. Blue: Motor Current. Red: Rotor Flux.
