MT Motori Electtrici is well known in Europe for its high quality and broad range of AC-Brake Motors. Above photos illustrate three of our standard two speed, 3 phase, IEC frame brake motors. The appearance and size is identical to the single speed brake motors.-
Left is the standard DF type, which features a rectified AC SAB type brake (an AC electromagnet holds back the springs that will close the brake should power be interrupted).
-
In the middle is a photo of a DFS which is supplied with a DC SAB brake (rectified DC is powered by terminal strip connection or by an control power feed). Very compact size.
-
On the right is our DFP series, which has a AC electromagnet over springs, this has the highest release and braking precision, the maximum braking frequency, and high starting frequency capabilities. DFP brakes have double braking surface for maximum precision and wear life. We can also supply DFP type with DC brake for softer braking.
