Mayr Transmissions has introduced ‘silent’ double-braked motors, in sizes ranging from IEC 71 through to IEC 132 frame, which are designed to be used in lifting and winching applications where double security and low operating noise is required, such as in theatre settings.

Motors can be either flange or foot mounted and fitted with either single or double brakes, all of which are available with a variety of options such as hand releases, wear/release monitoring switches, encoder shafts and a complete range of coil voltages.

These brake motors were introduced at the ABTT show in June, at London’s Royal Horticultural Halls, where they were displayed along with other products from Mayr’s range of torque limiters, shaft couplings and safety brakes.

Key specifications

  • Noise-damping technology keeps noise at less than 50dB(A)
  • Approved for EN81 and BGV C1 applications
  • Sizes range from IEC 71 to IEC 132 frame
  • Smaller motors (up to 1.5Kw 90 frame) can be supplied with Roba-secustop brakes
  • Larger motors supplied with industry-standard Roba-stop-silenzio brakes
