ELECTROMAGNETIC DRUM BRAKES

Electromagnetic Drum Brakes

 

Operating Principals:

  • Spring Applied Braking .
  • Releasing using Electromagnetic Actuator.
  • Adjustable braking torque.

 

Construction:

  • The brake spring and brake lifter are laterally positioned.

  • Brake shoe lifter with single web construction.

  • Synchronous releasing mechanism.

Special Characteristics of the Brake-Type Binsi

 

  • All requirements of DIN 15435 are fulfilled, therefore assuring interchangeability.

  • High braking torque independent of the direction of rotation due to optimized lever geometry in connection with increased stiffness of the base plate and brake shoe lever.

  • Good lateral stability of the brake due to widened base of the brake shoe lever.

  • Synchronous releasing mechanism and brake shoe clamps guarantee a self-adjusting constant gap on the brake linings.

  • Increased safety due to tension bar structured with small stress concentration:

  • Encased tension bar threads enable an easy adjustment of the brake even under adverse operating conditions.

  • Bolts made of electroplated steel and box bearings increase their reliability of operation and life of the brake, all standard parts are galvanized.

  • The enclosed spring tube protects the brake spring against damage.

  • Simple adjustment of braking torque, easy-to-read torque scale.

  • Changing the brake shoes without dismantling the brake is possible.

  • According to DIN 15435, brake shoes are cast in light metal and boxed with steel bushes.

  • Brake linings, bonded type with a coefficient of friction of 0.4

  • Finish - Pacific blue.

 

Brake units fitted with standard silicon rectifier attachment. Units are available with built-in silicon rectifier suitable for direct AC mains connections of 380 or 525V three-phase. Brake operating coils are wound for 168 and 220V DC respectively.

Brake units with Force voltage silicon rectifier attachment. This rectifier unit is a special force voltage type, which for a limited period, supplies the brake with its nominal DC operating voltage.

This reduces the normal brake release time by 40%.
