Three-phase brake motor BAH-BAHX series

asynchronous230 V400 V

BA electric brake motors are supplied as standard as BAH series starting from the frame size 225 up to 315 mm and on request starting from the frame size 80 up to 200. BAH series brake motors are proposed in the BAHX version for continuous duty with efficiency class IE2 / IE3 (compliant with EU regulation 2019/1781), alternatively they can be supplied in the BAH ‘Enhanced Power’ version only for intermittent service (S3 60%). The BAH series brake motors have the same characteristics of the BA-BAX serie-motors. The difference essentially consists in the casing of the brake assembly designed to give greater strenght and protection against the entry of dust and liquids (IP degree). The BAH serie-motors are supplied as standard with IP55 protection degree and, on request, with IP56-65-66 protection degree. Starting from frame size 160 casing, shields, flanges, brake friction surface and the brake protective cover are made of cast iron in order to provide a greater mechanical strenght and to be suitable for harsh environment (i.e. marine application). Upon request, starting from frame size 225, the motor body can be made of ductile cast iron. Starting from frame size 160 shafts are made of 39NiCrMo3 steel. The standard brake release is the locking type (on request it’s possible to have the unlocking one). The locking type brake release is realized by means of 1 central screw for sizes 80÷112, 2 side screws for sizes 132÷315. The BAH series motors are also available in the BAHS execution without cooloing fan.
