Brake Motors are offered for various
applications requiring almost instantaneous
stopping of driven load. These motors are
offered in frame sizes 71 to 132M. Their
operation is of ‘fail safe’ type, i.e., the brake is
applied when, power to the motor is switched
off, or, if power failure occurs.
Construction
A Brake Motor is an integral combination of
an A.C. induction motor and a disc type, fail
safe, electromagnetic brake unit. it consist of
following:
i) A.C. induction motor.
ii) Encapsulated brake coil housed in the nondriving end End-shield.
iii) Brake liner attached to the armature disc
at its interface with the cooling fan.
iv) Cooling fan.
v) The rectifier unit is provided inside the
Terminal Box. it converts A.C. supply into D.C.
supply for the Brake coil.
