VFD braking with DC current
VFD braking with DC current
(OP)
Good morning everybody,
I would like to understand better (from the theorical point of view) what is the physics
of braking with DC. Can you suggest me something to read?
Thank you

However, if none of this options is available or the brake chopper is as it's temperature limit, some VFD are also capable of DC-braking.
The disadvantages of DC braking are:
- variable torque according to motor characteristics
- energy is dissipated mainly within the motor
