Demag KBA conical-rotor brake motors feature squirrel-cage rotors and provide high starting torque. They are mainly designed as starting and stopping drives, but are also suitable for most other dynamic drive applications.

KBA motors can be connected direct to a line supply or fed by frequency inverter. They are available for S 1 continuous duty with 100% CDF or S 3 intermittent duty with 60, 40, 25 or 15% CDF.

KBA motors offer considerable thermal reserve capacity for particularly high switching frequency thanks to IP 54 enclosure and insulation class F. The model and terminal boy position can be adapted to the installation situation - also at a later date.

KBA motors are available with 2, 4, and 6 poles. They can also be supplied as pole-changing units, e.g. with 8/2, 12/2 and 12/4 poles with separate windings, as well as 8/4 poles with Dahlander winding. You can order motors for the standard 400 V IEC supply as well as for special voltages ranging from 380 to 415 and 600 V.

Their braking characteristics can be adapted to specific requirements by fitting brake springs of different strengths and due to the possibility of specifically influencing the moment of inertia.
