A DC injection unit is an electronic device that provides smooth frictionless braking of ac motors. It doesn't use brake discs or shoes so doesn't wear out or need maintenance.
It creates a DC stationary 0Hz magnetic field in place of the rotating 50Hz field. This brakes the rotor until it's also stationary.
The addition of a DC injection brake to an existing machine can be as simple as replacing the existing starter and fitting a new starter with built-in braking unit.
Safety and machine limitations must be taken in to account. See DC injection braking sizing notes (available on request).
We have a range of units that offer an economical electrical solution to the requirement of motor braking.
Please note that all our DC braking units are built and designed in house. If you have specific requirements, please contact us to discuss your needs.
