Inspection / maintenance of the BMG02 brake
Measure the
brake disk
thickness, install
a new brake
BMG02
The status of the brake disk is ascertained by measuring the brake disk thickness. Install
a new BMG02 brake once the brake disk thickness reaches the minimum value (
→
fig-
ure below). It is not possible to adjust the working air gap.
1. Isolate the motor and brake from the supply, safeguarding them against
unintentional power-up.
2. Unscrew the hand lever [1] (on version with manual brake release), remove the fan
guard and the fan.
3. Loosen the screws [2] and remove the complete brake with the releasing lever (on
version with manual brake release).
4. Measure the thickness "d" of the brake disk [3]:
5. Replace the complete brake if the brake disk thickness has reached the
minimum value.
6. Install the complete brake in the motor:
– Make sure that the gearing of the brake disk [4] engages in the gearing of the
carrier [5]
– Route the electric connection leads through the non drive-end bearing shield and
the inside of the motor into the terminal box
7. Use screws [2] to install the brake back onto the non drive-end bearing shield
8. Refit the fan and fan guard, screw the hand lever [1] (on version with manual brake
release)
