Conical Rotor Brake Motors

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 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.High-performance motor
Motor output up to 88 HP (55 kW) (at 40% CDF)
2, 4, 6 or 8 poles
Two-speed motors
KBA for starting-and-stopping drives
KBF for direct line-fed travel motions
Extremely robust brake
No switching elements needed
No separate control needed
Long brake lining service life thanks to effective dissipation of heat generated by the brake (through large surface area of brake cover)
Short overall length and good heat dissipation (brake disc simultaneously forms the motor fan)
Two brake disc designs – light for KBA motors, heavy and with increased moment of inertia for KBF motors
Extremely high switching frequency permitted
Resistance to temporary overload
