SUPERSET XL
AUTO-BRAKING MOTOR
19-3 “LAFERT” AUTO-BRAKING MOTOR
MAINTENANCE
All interventions must always be carried out disconnecting the power line which feeds the motor and the brake.
For this operation, act on the main switch located on the electric panel.
REGULAR MAINTENANCE
Remove the fan cover hood (Part 17) by unscrewing the self-tapping screws.
With compressed air remove dust, wood shavings or other particles which have deposited on the brake system
and on the motor body.
Insert a thickness gauge between part 43 (electromagnet) and part 37 (mobile core).
Check that there is an air space (air gap) of between 0.4 and 0.6 mm around the entire circumference.
If the air gap value reaches 0.8 mm there is no mechanical braking. Thus, the air gap will have to be reset and
the brake disk replaced (cooling fan) part 36.
For safety reasons, it is recommended the reset the air gap at an intermediate value between the limits indicated
above.
RESETTING THE AIR GAP
Having removed the fan cover hood (part 17), straighten the twisted tab of the safety washer (part 57) with a
metallic point.
With a tool, screw the ring nut (part 58) as much as necessary so that the air gap (distance at point TR), measured
with a thickness gauge, is reset to a minimum value of 0.4 mm on one side and to a maximum of 0.6 mm on the
opposite side.
Make a notch of the ring nut (part 58) coincide with a tab of the safety washer (part 57) by slightly screwing or
unscrewing the ring nut (part 58), and bending the tab to where it originally was.
Having rechecked the air gap, remount the external protection hood (part 17), and after reactivating the electric
panel, check proper functioning by starting and stopping the machine.
REPLACEMENT OF FAN WITH FRICTION DISK
Lift the tab of the safety washer, as for air gap resetting, and after completely unscrewing the ring nut (part 58)
and removing the safety washer (part 57), axially remove the fan (part 36) from the gear housing.
Having replaced the fan with a new one, first re-insert the washer (part 57), then the ring nut screwing it until
resetting the air gap as previously described.
It is recommended to carry out the fan replacement operation with the motor placed on a work bench and with
the spindle turned towards the bottom to prevent the springs (part 38) from falling out.
N.B.
a)
For electrical repairs it is recommended to contact an authorised LAFERT dealer or the
machine manufacturer
b)
The electrical connections of the motor and the brake must be carried out according to the
diagrams supplied.
