Product Description

INTRODUCTION
CONSTRUCTION : Brake Motors are used for various applications, where instantaneous stopping of the driven load is required. The operation of the brake is "FAIL SAFE TYPE"i.e. normally ON> When the electrical power to the motor is cut-off or the power fails, the brake is applied. Brake Motor is a combination of an A.C. induction motor and an electromagnetic AC or DC brake. The electromagnetic brake is mounted on the non-driving end of the motor. DC brake motors are provided with a rectifier which provides the required DC voltage to the brake coil which in turn operates the brake. the supply to the rectifier is fed from any two terminals(between any two phases) in the main terminal box of the motor. General applications of the Brake motors are printing machinery, textile machinery, rolling mills, cranes, Hoists, material handling equipments, machine tools etc.

WORKING : when the power to the motor is switched off, a braking torque is generated which presses the armature plate of the brake against the mounting flange. When the supply resumes, a magnetic field is produced i9n the brake coil and this pulls the armature plate against the spring force and the shaft is now free to rotate.

RANGE OF HINDUSTAN BRAND BRAKE MOTORS :
Kw RPM Mounting Frame Voltage Frequency Braking torque . Brake coil voltage Degree of protection Duty cycle	: 0.*3 to 5.0 KW : *0,0,0,0. : foot (B3), flange(B5) : face (B4)& combinations : 3 to 0 L : 5 Volts /as required : 0 Hz. : up to 0 Nm : 0 v Dc (Other voltages on request) : IP4 : S*-S8.

SPECIAL FEATURES : • Brake motors are simple & rugged .So easy for maintenance. • No seperate DC supply is required as the rectifier is priovided which gives the required DC voltage for energisation of the brake. • The rectifier is mounted inside the main terminal box so no seperate terminal box is required.

GENERAL GUIDELINES FOR THE SELECTION OF SUITABLE BRAKE MODEL :
The brakes are rated by torque & selection of suitable model can be made by calculating the required torque, rating of the brake & then matching it with static torque.
Torque(Nm)= ***0x(KW/RPM)XSAFETY FACTOR(sf)-where Kw*- Kilowatts of motor.
RPM*- Speed of motor
SF*-Safety factor depending upon type of prime mover & load.
For Electric motor*- SF=2 to 3
For diesel engine*- SF=4 to 5
For compressor- SF=5 to 6.

BRAKE COIL CONNECTION DIAGRAM :

Brake coil is energized by DC side switching as shown in the diagram.
