Demag Cranes & Components  has released the KB conical-rotor brake motor. The Demag KB conical-rotor brake motor provides you with a brake motor that utilises a unique operating principle.

The brake is not separately controlled, but firmly connected to the rotor, i.e. integrated. This means that motor start-up and brake release as well as motor switch-off and brake application are each synchronised.


The Demag KB conical-rotor brake motor features a remarkably simple, robust and reliable brake system. It is an ideal solution wherever demanding requirements have to be met by the brake.


  • High switching frequency
  • High braking energy
  • Unaffected by temporary overload
  • Long brake lining service life, since the heat generated by the brake is immediately dissipated
  • Short overall length, since the brake disc simultaneously forms the motor fan
  • No separate control or additional switching elements required, since the brake is automatically applied and released
  • No additional motor temperature rise, since a brake coil is not necessary

Demag Z cylindrical-rotor motors:

Demag Z cylindrical-rotor motors are designed for optimum integration with Demag gearboxes and their design configurations to suit your needs.

The output ratings of the 2, 4, 6 and 8-pole motors are graded according to the IEC classification. The motors are also available as pole-changing units or with an integrated flywheel for particularly smooth motions.

The housings of motor frame sizes Z63 to Z132 are of high-quality aluminium alloy, guaranteeing high stability for a low deadweight. Motor frame sizes Z160 to Z180 feature grey cast iron housing.
