KB conical-rotor brake motors - reliable partners

KB conical-rotor brake motors

for particularly demanding braking action

Demag KB conical-rotor brake motors with outputs of

up to 55 kW and a cyclic duration factor of 40% work

on a unique braking principle:

■ simple

■ robust

■ reliable.

Simply brilliant - brilliantly simple

The brake is mechanically linked to the rotor. When the

motor is switched on, the conical design causes force to

be applied in an axial direction, which pulls the rotor

towards the drive end together with the brake disk.

The advantage of simplicity

■ No switching elements required for the brake:

separate controller not needed

■ Heat generated during braking is effectively dissipated

via the large-format brake cap: longer service lives for

the brake linings

■ The brake disc is, at the same time, the fan:

reduced housing length, good heat dissipation

■ Two designs of brake disc: light-weight version for

KBA motors, heavy version with increased moment

of inertia for KBF motors.

Always the right conical rotor for your application

Alongside the 2, 4, 6 and 8 pole and the pole-changing

versions, there are two special KB series:

■ KBA for starting/stopping applications

with short cycle times

KBF for line-fed travel motions.

In addition, there is the KBS motor, a version

with special windings for standstill operation.

For outputs of up to 55 kW: Four-pole KBA motors
