DC injection braking is a method of slowing AC electric motors. Direct Current is injected into the winding of the AC motor after the AC voltage is disconnected, providing braking force to the rotor. [ 1 ]
DC injection braking A method of slowing an AC electric motor by passing direct current through its windings. DC-to-DC converter A circuit that takes power from a DC source and generates a different DC voltage. degaussing The process of reducing the residual magnetic field in a metallic object, such as a ship. delay line
During flux braking the motor is under DTC control which guarantees that braking can be made according to the specified speed ramp. This is very different from the DC injection braking typically used in drives. In the DC injection method DC current is injected to the motor so that control of the motor flux is lost during braking.

In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
Schematic symbol of a slip ring motor. A wound-rotor motor, also known as slip ring-rotor motor, is a type of induction motor where the rotor windings are connected through slip rings to external resistance.

A unipolar motor (also called homopolar motor) is a direct current (DC) motor typically with slip-rings on each end of a cylindrical rotor and field magnets or a DC field winding generating a magnetic field on the stator. The rotor has typically not a winding but just straight connections in axial direction between the slip-rings (e.g. a copper ...
