Dear sirs,
Currently i am working on a project. I have a ac induction motor 11kw which is operated by star delta contactor switching. This motor does not have any mechanical brake. The problem is i want to stop the motor from free run when the power is cut off from the motor. I am aware that there is a method by injection the dc voltage to the ac motor coil will brake the motor. i do not have any knowledge on this and i could not find any books on this either. Please advise how could i stop the motor by injecting the dc voltage.
for your info, my motor is rated 11kw, 3 phase, 4 pole, 415 VAC, 50 Hz.
Please advise me
Thanks in advance
