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 single speed, 3 phase, IEC frame brake motors.

  • Left is the standard TF 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). The brake we use is from Officini Elettromeccanica Gottifredi (O.E.G.) FM series for DC rectified and MS/FM for AC type.  to learn more about this brake click its link.

  • In the middle right is a photo of a TFS 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.   The brake we use is from Officini Elettromeccanica Gottifredi (O.E.G.) MLCC series for DC rectified compact braking. to learn more about this brake click its link.

  • On the bottom is our TFP 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.  TFP brakes have double braking surface for maximum precision and wear life.  We can also supply TFP type with DC brake for softer braking.   The brake we typically use on the TFP made by Officini Elettromeccanica Gottifredi (O.E.G.) and is their SMS Series.  To learn more about the SMS series used in the TFP, click the SMS series link.
