Simple, robust and reliable Conical-rotor brake motors Starting and stopping with maximum performance Simple, robust and reliable – these are the key characteristics of our KB conical-rotor brake motors. Their unique brake operating principle eliminates the need for separate control or additional switching elements. This is due to the mechanical connection between the brake and rotor. The result: particularly high braking performance approval for operation with extremely high switching frequencies two-speed pole-changing motors drives for starting-and-stopping applications and for direct line-fed travel motions resistance to temporary overload KB motors can be connected to gearboxes via a coupling.
