Injection braking

WebbDC injection braking involves applying DC voltage to the AC induction motor’s stator winding. This generates an opposing magnetic field that slows the motor down. The disadvantage of this method is that maximum braking torque is limited (approximately 66% of full motor torque) and motor heating can be excessive. WebbIf the machine isolator is operated then power to the entire machine, including the braking unit, is cut off before the braking cycle has completed so the braking effect is lost. This has caused 'run down' accidents on machines fitted with DC injection braking when operators have approached the machinery for setting, not realising that the cutters were …
