Brake cover removing
Unscrew the brake cover screw cap (119). Unscrew the brake cover fixing cap (117). Remove the brake cover (26).
To reassemble the brake cover (26) proceed backward.
For the BAHE-BAHXE series motors, it is necessary, as first step, to proceed taking the encoder cover
(103) and the
encoder (102)
.
Braking Torque Adjustment
The brake torque is proportional to the springs (18) compression, which can be varied by operating
on the locknuts (20). The compression of the springs must be as uniform as possible.
On the table 2 and 3 the standard compression values (H std) of the brake springs are shown.
The corresponding brake torque of the standard compression values stated on the table are less than
the maximum braking torque stated on the motor nameplate, especially for AC brake assembly.
Please verify that the braking torque is suitable for your application.
If the brake coil (25) isn't able to call the brake moving element (24) back with a quick stroke and
keep it attracted without vibrations, verify the exact air gap adjustment and, if this inconvenience
still persists, loosen the locknut (20) and try it again until desired functioning is obtained.
After every intervention pls verify that the braking torque is the one required.
Never exceed the maximum braking torque value stated on the motor name plate. It's recommended to avoid
adjusting the braking torque to values lower than 40% of the maximum value.
For any clarifications, please contact the M.G.M. motori elettrici S.p.A. organization.
