BRAKE MOTOR

APPLICATION

A brake-motor is the combination of a standard motor with a braking electro-magnetic disk system. The brake is utilized to stop the motor and the machine it drives and hold them motionless. Brake-motors allow very short and precise times of stopping for rotating machines driven by a motor. Brake-motors are therefore used especially in handling systems where short and precise stops are required and in production lines where basic operating times have to be as short as possible. They also ensure emergency stops to provide operator and machine safety when a fault or damage occurs.

STANDARDS

Motors comply with the following standards and specifications;

IEC 34-1, IEC 34-2, IEC 34-5, IEC 34-7, IEC 34-9, IEC 34-14, IEC 72
TS 731, TS 732, TS 3067

FEATURES

In standard brakes DC voltage is used.
Standard insulation classes are B and F. Class H can be supplied as an option.
Motors are totally enclosed and have IP 54 protection class.
Brake assembly has a robust design.
Noise level of the brakes is below 70 dB.
In the standard execution the brakes are cooled by the motor fan..
Brake disks are made of 304 quality antimagnetic stainless steel.
The electro-magnetic winding is completely encased in a polyester resin.
All parts in the brake are coated against corrosion.

OPERATION OF THE BRAKE

Braking is provided by the friction of two mating surfaces. When power is fed to the brake-motor, the electro-magnet draws forward the armature (metal part), compresses the spring and releases the brake; the motor starts at the same time.

When power is cut off , the electro-magnet releases the armature and also the spring, which then tightens on the friction disk and applies a braking force.
