BRAKE MOTORS
BRAKE MOTORS
Navyug Electric offers Brake Motors. It is manufactured as per international standards. It is used for various applications requiring almost instantaneous stopping of the driven load. These motors are offered in frame sizes 63 to 225 m. 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 AC induction motor and a disc type, fail safe, electromagnetic brake unit. It consists of the following: AC induction motor encapsulated brake coil housed in the non-driving end-shield; brake liner attached to the armature disc at its interface with the cooling fan; cooling fan; and a rectifier unit provided inside the terminal box, which converts AC supply into DC supply for brake coils. Special features: simple and rugged construction, need very little maintenance; no separate DC supply is necessary; special brake liner is used; since the fan serves as a braking surface (unlike some other designs), it also serves to cool the brake coil and the motor; and for crane and hoist duty applications brake motors are offered with special rotors.
