What is a DC injection brake & how does it work?

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.
