ELECTROMAGNETIC BRAKE
Checking the electromagnet
If the brake, alternately energised and de-energised, does not release and
lock the brake lining correctly, measure the winding resistance, which should
be as follows:
80
Econ.
80
100
124
12 Volt brakes
5
8.3
4.5
24 Volt brakes
70
25
33
20
36 Volt brakes
62
85
34
48 Volt brakes
99
127
78
Also check insulation to motor, using a 500-volt Megohmmeter to measure
the insulation resistance, which must be above 0.1 M .
The electromagnet must be replaced if it does not fulfil these conditions.
Replacing the electromagnet and checking the lining with a splined hub
Remove any brake covers, completely loosen the three fixing screws and
remove the electromagnet and check the lining disk.
Its thickness must be about 7 mm for the type with diameter of 84 mm.; 8
mm for the type with diameter of 104 mm; and 8.5 mm for the type with
diameter of 124 mm.
If the thickness is, respectively, less than 5, 6 and 6.5 mm, it is advisable to
replace the complete lining of the splined hub after having removed the
Seeger ring or self-locking nut. Reassemble the new brake and proceed to
calibrate the clearance of the mobile disc.
Calibrating the clearance of the mobile disc
Calibration should be carried out as described below when replacing the
lining or the entire electromagnetic brake:
a. loosen the three hexagonal adjustment bushes
b. adjust the three fixing screws so as to obtain a clearance
between 0.2 and 0.4 mm;
lock the three hexagonal adjustment bushes and check, with a thickness
gauge, that the clearance is within the permitted limits.
